ABSTRACT
An investigation has been undertaken into the extended use of ESDA (Electrostatic Detection Apparatus) instrumentation for document examination, specifically in terms of its use for enhancing marks on various grades in terms of grams per square meter (gsm) of paper and for marks on semi-charred documents. It was determined that the best marks could be recovered from the heavier grades of paper and that marks could be recovered from paper that had been exposed to temperatures up to 300oC, just before the paper becomes carbonized.
The study called into doubt the accepted position that humidifying paper resulted in the enhancement of marks and suggested that this phenomenon could be variable with respect to a function of the ambient conditions of the environment where the paper was being investigated and the grade and make of paper concerned.
A detailed investigation was undertaken into the use of Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) for determining the provenance of paper, paper ash, ink and pencil leads. In addition, a detailed study was undertaken to develop a method of determining the chemical signature of ballpoint pen ink on paper using Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) and tracing that signature back to the original batch of ink used.
Investigations into the provenance of paper were able to confirm that the element distribution pattern (chemical fingerprint) within single sheets and single reams of paper were statistically indistinguishable and that individual batches of paper had the same chemical signature. In addition, it was able to be confirmed that Australian paper has a generic signature that can distinguish it from paper made in other countries around the world. It is distinctly possible that this type of generic signature exists for other countries of manufacture of paper, where the manufacturing process is automated and paper is made on a large scale. However, to investigate this aspect is beyond the scope of this thesis. Eighty-five reams of paper from around the world were used in this study.
In addition, paper that has been completely ashed was proven to be unambiguously traced back to the original unburned paper it came from, and it is therefore possible to unambiguously confirm whether or not ashed papers have, or have not, a common chemical signature with un-ashed material that may also be recovered in the course of a criminal investigation. It is also appears to be possible to determine whether or not “old-growth” forest has been used to produce paper, which is an extremely important environmental safeguard for the preservation of indigenous forest throughout the world from unscrupulous logging and chipping for this purpose.
Individual ballpoint pen inks were chemically analysed to determine their element distribution pattern (chemical fingerprint). This chemical fingerprint is also unambiguously associated with a batch of manufacture and can be used to relate specific pens back to recovered evidence.
6
Although it may appear obvious what colour an ink is by simple visual comparison, it may not be as easy to distinguish between them as one may wish when ink colours are close together. Consequently, the individual inter element association pattern of each ink has been determined to facilitate unambiguous comparison to a reference data base of inks with the equivalent colour and overcome any false positive and false negative identification simply on the basis of colour of the ink. Even with the same colour inks, and the same manufacturer of these inks, differences in the trace element signatures of the individual inks occur and can be easily identified and lead to the proposition that each batch of ink has a separate trace element signature. Consequently, an individual ink can be traced back to its batch of origin or compared with recovered relevant material from the crime scene, or from follow up investigations, to determine matches. One hundred and eighty six ballpoint pens from around the world were used in this study.
While there are obvious differences in the trace element association patterns for individual batches of ballpoint pen ink, at this stage there appears to be limited data that could confirm the existence of generic trace element signatures for the same colour ballpoint pen inks from individual countries.
Research into the unique identification of one hundred and eight bottles of fountain pen inks manufactured around the world has confirmed that the chemical signature of these inks from the same manufacturer and same batch are statistically indistinguishable. In addition, it is statistically possible to identify batch differences between inks and to determine the country of origin, and, perhaps more surprisingly, to determine that some very expensive inks (for example Cross and Pelican) are made in the same country, by the same manufacturer and are identical in chemical composition, but are sold at completely different prices. It can be assumed that this practice occurs universally and that customers are being charged prices that do not reflect the quality of the product.
The inter-element association patterns (chemical fingerprints) of one hundred and twenty seven pencils, manufactured in different countries around the world, have been investigated using LA-ICP-MS. Elements, present in individual different batches of the same manufacturer have discernible differences in their chemical fingerprint while there is excellent reproducibility between the chemical signatures of pencil leads from the same batch. There is also a noticeable difference between the chemical signatures of different hardness’s of pencils from the same manufacturer and equivalently from and between different manufacturers. It is therefore equally as easy to identify the chemical signatures of pencil leads and to assign these signatures to specific pencils or to pencil lead data that have been entered into a data base. The fact that pencils are not accepted for signing legal documents means that this research has somewhat limited use in forensic investigations. However, it does represent a completeness in the methodology that has been developed to determine the provenance of hand held writing instruments.
It has been possible to isolate the chemical fingerprint ballpoint pen inks after they have been applied to paper, and to link this back to an individual ink in a data base of inks. In this investigation, LA-ICP-MS was used as the investigative technique, and a laser was used to traverse across drawn ballpoint pen ink lines on different manufacturer’s brands of paper. The analytical data produced obviously incorporated the chemical fingerprint of the paper,
7
and the ink and it was not a simple matter of blank subtraction to remove the signal of the one from that of the other to obtain the ink signature. Many of the analytes involved, when corrected were below the detection limits of the technique and consequently only a limited set of twenty-seven analytes from the sixty-two determined were present in sufficient concentrations to be useful for determining the chemical composition of the inks involved in the study.
In addition, because of variations in the background major-analyte composition of the paper, due to fillers and dust etc. incorporation, it was necessary to interpret all data manually and to use subjective (experience) background definition to determine blanks for each analyte in each sample. This resulted in the manual correction of nearly four and a half thousand data points to obtain the final data set.
It was however confirmed that a single traverse (100μm wide) across an ink mark is capable of providing a chemical fingerprint of the ink involved and that that chemical fingerprint can be traced back, irrespective of the paper it is written on, to a unique batch of ballpoint pen ink. This aspect is of major significance to document examiners as it provides indisputable proof of origin of these types of ink and can also be used in cross comparison in the case of different pens, even the same brand, being used to falsify documents.
A combination of the protocols detailed in this thesis adds a new and significant arsenal to that already available to the forensic document examiner and, when used in combination with traditional investigational data, can provide unambiguous and compelling scientific evidence to assist examiners in determining whether documents have been falsified, added to or are unique and genuine.

Chapter 1 Introduction 1.1 Paper
1.1.1 History of Paper
The word “paper” is derived from the Egyptian word “papyrus” (Achtemeier, Green et al.,
2001). Papyrus refers both to a reed, which flourished along the Nile River, and to the paper
like material made from the plant and which was used for recording written material from as
early as 3000 BC (Wiedeman and Bayer, 1983). The ancient Egyptians made papyrus sheets
by removing the reed’s outer skin and cutting the centre into thin strips (Wiedeman and
Bayer, 1983) The strips were laid side by side and a second layer was placed on top of the
first at right angles (Wiedeman and Bayer, 1983). The combined strips were then hammered
into a single sheet, being bound by a secretion which was released from the plant (Asunción,
2003). The resultant papyrus sheets were lightweight, portable, and ideal for writing on and
became the writing medium of choice for various cultures in the ancient world up to
relatively modern times (Christensen and Wegner, 2009).
However, papyrus sheets are not true paper in the sense of macerating and mixing fibres
(Twede et al., 2014). Paper as we know it today, was the invention of Ts’ai-Lun, a Chinese
imperial court official in 105AD (Twede et al., 2014). Ts’ai-Lun’s method, which is
fundamentally the same as that used today, involved softening mulberry bark with lime,
mixing it with linen and hemp and then beating the mixture into a pulp (Twede and Selke,
2005). Having been kept a secret in China for centuries, the art of papermaking slowly spread
along the Silk Road, reaching Central Asian by the 4th century (Herbert, 2006). Later the
techniques of paper making travelled west, firstly to Turkestan and then to the Arabic
countries in 751AD, reaching Europe by the 12th century (Asunción, 2003).
Once exposed to European demand important developments soon followed with the
invention of the printing press by Gutenberg in 1450, which brought about an enormous
increase in the demand for paper worldwide. At the end of the 17th century, a mechanical
beater known as the “Hollander” which worked as a wood pulp beater to break down the
21
pulp and separate it, was developed, and most notably the “Fourdrinier” or paper machine,
which forms the paper
into a continuous web, was developed in 1798 (Saltman, 1978). The Fourdrinier is a multi-
cylinder machine which produces paper on an endless wire screen on which a fibre slurry is
deposited to form a matt from which the water is then drained leaving a continuous integral
sheet of paper. This process is essentially that used today and is the basis of the modern
paper industry. Prior to this invention, paper was hand-made one sheet at a time.
1.1.2 Papermaking
Today papermaking involves fundamentally the same steps as have been used for centuries;
namely preparation of the fibre material, sheet or web forming, pressing, drying, and
smoothing (Herbert, 2006).
Wood, which is made up of small cellulose fibres bound together by a glue-like substance
called lignin, is the basic raw material for the papermaking process. First the wood is chipped
into small pieces, which are then mixed with chemicals such as sodium hydroxide, and
sodium sulphide, and fed into digesters (known as pressure vessels) to dissolve the lignin and
separate the pulp fibres (Koppenhaver, 2007). The fibres are then washed with water and
screened to remove any clumps. Bleach may then be applied to remove any lignin remaining
in the pulp and to achieve the desired level of brightness. This procedures is necessary
because lignin contains chromophoric groups which generally impart a brown colouration to
the pulp mass (Saltman, 1978).
The fibres are then combined with pigments, dyes and size, a solution containing modified
starches and sometimes gelatine which adheres to substrate fibres and forms a smooth
water-repellent surface which improves the strength and printability of the paper. Optical
brighteners and fillers can also be added at this stage. The resulting mix contains over 99%
water and less than 1% fibre and other solids (Koppenhaver, 2007). This mixture flows onto
an endless moving wire screen (known as a Fourdrinier) on which the water is drained and
the fibres form a loose matt (Saltman, 1978).
22
The sheet then passes through heavy rollers which squeeze out the majority of the moisture
and is then dried over steam-cylinders to evaporate any remaining water and cause the fibre
bonds to set. Following this procedure, the paper is smoothed by passing through a series of
iron rollers known as calendar stacks (Koppenhaver, 2007). Pressing also adds gloss and
results in a higher density (Saltman, 1978). Finally the resultant paper is cut into the required
dimensions (Ellen, 2005).
1.1.3 Paper Uses
Although, with the advent of the “electronic age” and the Internet, and the rise of “Green
Politics” the amount of paper used is being reduced, as a medium paper still is the worldwide
medium for printed communication. It is also used in a wide variety of different ways and is
produced in a variety of forms including newsprint (newspapers), finished paper, offset paper
for books, opaque paper, coated paper and coloured paper (Saltman, 1978). Research
detailed in this thesis concentrates primarily on examination of ‘all purpose’ and copier paper
from various manufacturers and countries of origin Section 3.3 Table 3.3 as it is the most
widely used and available base for the written word.
1.2 Inks and Pens
1.2.1 History of Inks and Pens
Ink and pens have been in existence for over 5000 years. The earliest pens consisted of
hollow straws or reeds that held small amounts of ink (Lander, 1988). This type of pen was
superseded by the invention of quill pens which used the strong primary feathers of birds
such as geese and swans (Koppenhaver, 2007). In fact the word pen is derived from the word
“penna”, meaning feather in Latin (Koppenhaver, 2007).
It was not until 1784 that the first steel pen was manufactured (Koppenhaver, 2007) and by
1822 Joseph Gillot had devised the steel pen press which produced pens in large quantities
with high precision and little cost, leading to mass production. In 1884 Lewis E. Waterman
patented the first practical fountain pen, which had to be filled with ink using an eyedropper
23
(Koppenhaver, 2007). In 1913 Walter A Schaeffer invented the level-filler fountain pen.
Modern fountain pens draw ink from an internal reservoir of ink through a metal nib (writing
tip) (Cavendish, 2002). The ink is deposited onto paper through a combination of capillary
action and surface tension between the tip of the pen and the paper (Cavendish, 2002).
The first ballpoint pen was patented in 1888 by John Loud, however it was too coarse for
writing and commercially non-viable (Brunelle and Reed, 1984). It was not until 1945 that
ballpoint pens became popular after several improvements to the original design were made
(Koppenhaver, 2007). A ballpoint pen consists of four parts, the ink, tube, ball and ball holder.
(Koppenhaver, 2007). When it is used, the ink dispenses at its tip by the rolling action of the
pinhead-sized metal ball (Erol et al., 2004). The main problem was to maintain the viscosity of
the ink without the ink crystallizing or becoming a gel as this led to ink leakages or clogging
(Koppenhaver, 2007).
In 1938 Laszlo Jozsef Bíró patented a ballpoint pen which, much like ballpoint pens today,
used quick-drying ink and a small ball in its tip that was free to turn in a socket and suctioned
ink from the internal reservoir (Biro, US Patent No. 2265055A). This pen used capillary action
and a piston that pressurised the ink column, solving the ink delivery flow problems.
Fibre tip, porous or felt tip pens were first manufactured in 1963 (Koppenhaver, 2007). They
draw a liquid ink from an internal reservoir to the tip in a controlled leakage (Hechtle, US
Patent No. 3353899A). The first roller ball pen was invented in 1963 (Koppenhaver, 2007)
and made use of a mobile ball in its tip. However, unlike a ballpoint pen, it has more fluid ink
which flows more readily onto paper (Erol, 2004). Commonly a water-based ink is used
(Koppenhaver, 2007). Gel pens are the most recent innovation and contain permanent gel in
a liquid solution which is fade proof (Koppenhaver, 2007). These pens are highly resistant to
most common solvents and water and this complicates forensic analysis since it is necessary
to extract the ink using a suitable solvent before analysis can take place (Verma et al., 1979).
24
1.2.2 Identification of Pen Marks
The type of pen used can be identified through examining the characteristics of the pen and
the ink used. The fountain pen consists of two parallel steel ‘nibs’ that when moved against
paper they slightly break through or penetrate the paper leaving an ink line along the groves
(Kobilinsky, 2012 p.234). In contrast, the ball point pen simply rolls ink onto the paper by
means of a small ball and only leaves a groove in the paper in the centre of the line of ink,
which can be seen under a microscope. (Koppenhaver, 2007). This heavy ink sits on the paper
surface and generally may be characterized as being shiny. These pens are susceptible to
‘gooping’ (where ink collects on the ball of the pen and is dispersed in an excessive amount)
and sometimes leave blank spots in the ink line (known as burr striations) where the ball
failed to deposit ink on the paper because the ink clogged (Koppenhaver, 2007).
1.2.3 Composition of inks
1.2.3.1 Fountain pen inks
The two main types of ink used in modern fountain pens are solutions containing iron gallate
or synthetic dyes (Siegel et al., 2013). The iron gallotannate type consists of iron salts and
gallotannic acid in an aqueous solution which is colourless when first applied to paper but
quickly darkens upon oxidation in air (Brenner, 2004 p.146). Such inks are very stable, rapidly
absorb into the paper fibre, are insoluble in water and cannot be effectively removed by
abrasion (Brunelle and Reed, 1984).
1.2.3.2 Ballpoint pen inks
Ball point pen inks consist of synthetic dyes dissolved in glycol (such as propylene glycol or
butylene glycol) or alcohol (such as benzyl alcohol). Modern inks contain dyes that are highly
soluble in the glycol or alcohol (Brunelle and Reed, 1984). The most common dyes are blue
and based on the compound copper phthalocyanine and are treated by sulfonating or
chlorosulfonating copper phthalocyanine pigment (Brunelle and Reed, 1984). Other pre-
metalized dyes, such as reds, greens and yellows, are similarly treated (Brunelle and Reed,
1984).
25
1.3 Pencils
1.3.1 The History of Pencils
The history of pencils can be traced to the Ancient Egyptians and Romans, who used a thin
rod known as a ‘stylus’ to impress a mark into wax or wet-clay (Blaxland, 2008). However
pencils as we know them today only developed with the discovery of graphite deposits in
Bavaria in the 1400’s (Cain et al., 1978). These graphite deposits were called ”plumbago”
which in Latin translates to ‘acting like lead’ a word which continues to lend itself to the
name ‘lead pencil’ (Cain et al., 1978). Graphite was first held together in a variety of forms
including sheepskin and sticks and finally wooden hollow sticks which were developed by
Simonio and Lyndiana Bernacotti in 1565 (Blaxland, 2008).
The first commercial production of pencils was instigated after the discovery of the
Borrowdale graphite deposit in Cumberland England in 1564, from which very high purity
graphite blocks were mined and cut into thin strip rods and inserted into wood veneers (Cain
et al., 1978). By the mid 1700’s, as high grade graphite became extremely valuable and high
grade graphite deposits were becoming depleted, attempts were made to create
concentrates and mixes of graphite that were cheaper and could be used for pencils (Cain et
al., 1978). In 1795 a French scientist, Nicholas Jacques Conte, developed the process for
producing black “lead” pencils which is still used today (Blaxland, 2008; Cain et al., 1978). This
process, which gave birth to the modern pencil, was achieved by mixing powdered graphite
with ground clay and kiln-firing it to make pencil rods. By varying the proportions of graphite
and clay, the hardness and darkness of the product could be changed (Mandel, 1929). This
resulted in a less costly product that was relatively standardised (Cain et al., 1978). Conté's
method of combining graphite with clay is still used for the manufacture of pencil ‘leads’
today.
1.3.2 The Manufacture of Pencils
This process for the manufacture of pencils can involve more than 125 different steps (Cain
et al., 1978). Today’s pencils are largely produced by mixing finely ground graphite and clay
powders with water to from thin ‘string’ rods which are fired in a kiln.
26
Graphite is used for pencils that are mass produced and is mixed with a wide variety of other
chemicals so that the density of the final product can be controlled (Cain et al., 1978). This
material is mixed with clay in a variety of ratios to achieve the type and specifications of the
pencil required. The greater the proportion of graphite, the softer the pencil and the darker
the line whereas the greater portion of clay increases the hardness of the product (Brunelle
and Crawford, 2003) and produces lighter coloured lines.
The graphite and clay mixtures are then mixed and ground with water in a special ball mill for
several weeks. This process not only micronized the particles in the graphite and clay mix but
it also ensures a homogenous mixture product (Cain et al., 1978). Water is removed from this
mixture by flocculation, and the final “sludge” compressed and then fired in ‘string-shaped’
batches in a ceramic kiln (Cain et al., 1978). Once the graphite and clay mixture is fired and
set, waxes are applied in a pressurized bath for coating. There are a variety of different types
of waxes used, including stearic and tallow wax in various combinations, in this step in the
process; (Cain et al., 1978). The wax seeps into the microcellular structure of the graphite
mixture bonding the particles and making drawing smoother and giving the pencil the
relative shading qualities exhibited.
The next step in the manufacturing process is to overlay permanent castings around the
pencil. Thin wooden castings made from dried, stained and waxed cedar are most common,
although casings made out of plastic or paper may also be used (Burgelman, 1994). Once
cased, the pencils are then cut and shaped into either round, triangular or most commonly,
hexagonal cross Sections as this hexagonal design prevents them from easily rolling off flat
surfaces such as tables. The final step in the process, after the pencils have been shaped, is
for their surfaces to be smoothed and a varnish applied and dried.
For the manufacture of coloured pencils, colour pigments are added to the clay mix and very
little graphite is used.
27
1.3.3 Pencil Grades
The hardness and darkness of pencils is dependent on the portion of clay used. The greater
the portion of clay used, the harder the core of the pencil and the lighter the mark or
‘blackness’ as less graphite is deposited on the paper. The pencils first designed by Conte’s
were distinguished using a grading system with four numerical grades from “1” being the
hardest and “4” being the softest and darkest (Martin, 1997). As the Conté process for
manufacturing pencils became recognised and used by other pencil makers, similar grading
systems were developed. However, these grading systems were inconsistent and arbitrary
from one pencil manufacturer to another. During the early nineteenth century, English pencil
manufacturers began using a new alphabetical system for differentiating the hardness
between pencils. This new system originally ranged from ‘B’ for black for softer “leads” to ‘H’
for hard for harder “leads” and in the middle of this scale "HB" was included to signify “hard
and black” and “F” to indicate that that the pencil sharpens to a fine point (Cain et al., 1978).
To allow for a wider range, the system was expanded with letters from ‘BB’ and ‘BBB’ for
successively softer “leads” to ‘HH’ and ‘HHH’ for successively harder “leads” (Burgelman,
1994). However, the system was finally expanded to combine letters and numbers and allow
for a greater variety of grades with no more than two characters. This final expansion to
letters and numbers ranging from 9B to 9H is the same English system that is in use today
(Burgelman, 1994). This English system continues to indicate hardness by the letter ‘H’ and
softness by the letter ‘B’ for the blackness pencils, with the numbers indicating varying
degrees. The system is detailed in Table 1.1 and Fig. 1.1.
A second grading system also developed and was largely adopted by US pencil
manufacturers, becoming known as the ‘US system’ (Cain et al., 1978; Burgelman, 1994). This
US system used only numbers (1, 2, 2½, 3, 4) ranging from darker (1) to lighter (4), with
number “2” in the middle of the scale (Cain et al., 1978; Burgelman, 1994). This system was
developed in the United States by John Thoreau, and it is claimed that it was based on the
grading system originally created by Conte although inversed with Conte using higher
numbers to indicate softer “leads” and Thoreau using them to designate harder “leads”
(Burgelman, 1994). Today the most common pencil grade is the HB, equivalent to a “2” in the
28
US scale. Table 1.1 Conversion between US and English Grading System for Pencils is detailed
in Table 1.2 (Cain et al., 1978; Burgelman 1994).

Whilst today there are two primary grading systems used internationally (English and the US
system), there are no specific industry standards for manufacturing to these different grades.
Thus even for pencils with the same grades, there may be disparity between the marks left
on paper depending on the brand pencil (Cain et al., 1978).
1.4 General Overview - Documents and Crime
Paper and ink are important sources of evidence in crimes dealing with cases as diverse as
fraud, threats, ransoms, forgery and money counterfeiting. Documents play an important
role in solving crimes. For example, the so called “Hitler Diaries” fraud was a case that
involved the analysis of ink and paper (Hamilton, 2009; Harris, 2009; Michel and Baier, 1985).
9B
29
In 1981 Rupert Murdoch was committed to buying these diaries and publishing them. The
forger was known by the name of Konrad Kujau. The German police analysed the ink and
paper using chromatography and XRF respectively. These techniques revealed a whitening
agent that was not used in Hitler’s era as well as four different ink types which were not
available when Hitler was alive. The result of the enquiry was the arrest and successful
prosecution of Konrad Kujau for fraud.
Today, where documents are involved, Questioned Document Examiners (QDE’s) are often
required to perform procedures necessary to analyse the paper to determine its source,
identify and characterise markings, and often to enhance any markings or writing impressions
in order to help link the paper to an offence. In doing so, QDE’s can employ a number of
techniques and devices including physical examination (examination of weight, thickness,
fluorescence properties, opacity and water marks of the paper), chemical investigation of the
properties of the paper and ink and enhancement of impressions in underlying sheets of
paper, below that sheet on which the original message was written, using such techniques as
electrostatic detection apparatus (ESDA) to try and obtain a clearer image of what was
actually written on the original sheet. Many of these tests involve the use of “traditional”
techniques which, because of their longevity in the criminal arena, can be nullified by
judicious use of masking materials. Consequently, new scientific approaches for the
provenance determination of paper, inks and pencils and new techniques to enhance the
ESDA approach to enhance impressions need to be developed.
1.5 Previous Research
1.5.1. Paper
During the 1960’s and 1970’s several studies were undertaken which demonstrated the high
variability in the elemental composition of papers, produced by different manufacturers.
(Brunelle and Reed, 1984). These studies often confirmed that there were differences in the
chemical signature between batches of paper produced by different manufacturers (Ellen,
2005). However, as sample numbers increased the limited sensitivity of the analytical
techniques of the time, and limited number of analytes that could be determined,
30
significantly compromised the ability to distinguish between different paper batches.
Consequently, it became obvious that much more sensitive techniques needed to be applied
to the analysis of paper to ensure that a robust differentiation between both manufacturers
and batches of paper could be achieved. In 1971, thermal neutron activation analysis was
used in a study by Schlesinger and Settle to analyse 120 white paper samples from nine
different manufacturers. Their study not only indicated that samples from an individual
manufacturer could be grouped together but that a more chemically uniform product was
produced by some manufacturers than others (Schlesinger and Settle, 1971). An additional
study by Brunelle, Washington, Hoffman and Pro, using neutron activation analysis and
involving 600 samples of coloured and white paper from ten different manufacturers, found
that paper produced by the same manufacturer could be distinguished using quantitative
trace element analysis (Brunelle et al., 1971).
In 1974 Langmyhr, Thomassen and Massoumi used atomic absorption spectrophotometry to
determine the concentration of copper, lead, cadmium and manganese in paper pulp and
were able to differentiate between four different paper types; letterhead, chromatographic,
filter and greaseproof paper (Langmyhr et al., 1974). In 1975 Duewer and Kowalski used
pattern recognition software to interpret elemental data for white bond papers that had
been analysed using neutron activation analysis and confirmed that separation between the
papers produced by different manufacturers did occur (Duewer and Kowalski, 1975).
Scanning Electron Microscopy-Energy Dispersive X-ray Analysis (SEM-EDXRA) was used by
Barnard, Polk and Giessen in 1975 to determine the elemental composition of both paper
and ash from paper samples. However, their study confirmed that this technique could be
used satisfactorily only for the determination of major element concentrations in both
matrices. At the time, the study was considered as being particularly important as many
forensic science laboratories were purchasing SEM-EDXRA systems (Barnard et al., 1975). The
use of SEM-EDXRA to determine the elemental composition of paper was further developed
by Attard and Giessen who, together with Polk in 1977, found that differences in paper
batches were common (Attard et al., 1977).
31
In 1977, Simon, Giessen and Copeland, using atomic absorption spectrophotometry and
pattern recognition techniques to categorize paper, determined that copper, manganese,
antimony, chromium and cobalt were the most useful elements in distinguishing between
papers from different manufacturers. These authors also determined that density was an
important parameter in tracing paper back to the manufacturer (Simon et al., 1977).
In a study published in 1978, Blanchard and Harrison used neutron activation analysis to
determine the trace element compositional profiles of paper and used the ratios of specific
elements to identify fine paper. Initially these authors investigated the chemical composition
of clays from various sources which were being used as fillers for paper. Following this study,
they then tried to relate the elemental profiles of these clays to the chemical composition of
the paper that they were used to produce. The assumption was that the clay used gave a
unique chemical signature “fingerprint” to the individual batches of paper they were
incorporated into and that this fingerprint varied from batch to batch of clay or with
incorporation of multiply sourced clays into a single batch of paper. Their work successfully
resulted in a degree of comparability between clays and the final paper and also resulted in
one of the first databases detailing the chemical composition of paper being produced
(Blanchard and Harrison, 1978).
More recently in 2000, Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was used to
determine the elemental composition of white photocopy paper from 17 different sources.
The study by Spence, Baker and Byrne, which determined the concentrations of 23 elements
commonly, found in paper, they identified nine elements which could be used to distinguish
between the 17 papers. Of these nine they considered manganese and strontium to be the
most useful (Spence et al., 2000).
However, the problem still existed that the number of sources of paper analysed and the
range of analytes determined were limited and therefore the ability to distinguish between
different types of paper and between manufacturers in “real world” forensic situations was
still unsatisfactory. In 2009 initial research was undertaken using ICP-MS by McGaw et al. and
LA-ICP-MS by van Es et al., heralding the start of the use of high-sensitivity, modern analytical
techniques for the identification and provenancing of paper.
32
1.5.2 Ink
Chemical analysis of inks is often based around thin layer (TLC) or paper chromatography (PC)
and is a common type of technique used to differentiate between inks produced by different
manufacturers (Brunelle and Reed, 1984) . In 2009, a blind study by Naes used quantitative
chemical analysis to obtain a 95.6% discrimination between 45 black gel pen inks (Naes,
2009). This type of ink is the latest type of marker ink and it is extremely difficult to
determine its provenance.
Providing there is enough sample, chromatography-based separation and analysis techniques
are the most common ink analysis techniques used by forensic examiners. Usually a small
sample is removed from the questioned document using a scalpel or hole-punch. The ink is
then separated from the surrounding paper using an appropriate solvent. The resulting
solution can then be concentrated by evaporation and subjected to simple thin layer
chromatography (TLC) and the ink components separated into individual bands of colour that
form a “fingerprint” of the ink that can be easily compared with a reference sample. This
method is excellent for screening inks and gives a visible pattern that is easy for juries to
comprehend in court.
In 2006, Budnar et al. and Maind et al. applied PIXE and ICP-MS respectively directly to the
analysis of inks and in 2008 Maid et Al. tagged printing inks with europium as a tracing tool.
Analyses were undertaken using spectrofluorimetry and ICP-AES. In 2010, the first use of
mass spectrometric techniques for direct analysis of inks was undertaken by Trejos et al. and
Denman et al. Neither study was sufficiently comprehensive to facilitate incorporation of the
technique into general forensic practice.
1.5.3 Pencils
The analysis of pencil lead, to be able to distinguish between manufacturers, has proven to
be difficult (Brunelle and Crawford, 2003). In 1978 a study was undertaken to analyse the wax
component of the pencil lead using the technique of thin layer gas chromatography (TL-GC)
which did not prove that there are differences between pencil leads. In 1980, another study
33
was conducted using mass spectrometry to determine the elemental composition of pencil
“lead” cores. Data produced in this study was able to be used to discriminate between two
different manufacturers (Zoro and Totty, 1980).
1.5.4 Questioned Documents
Forensic document examination, referred to in some countries as “questioned document
examination”, is a branch of forensic science that relates to the examination of any type of
documentary evidence in both civil and criminal investigations. A document is anything upon
which a mark is made for the purposes of conveying a message and a questioned document
is one where there is some doubt or dispute regarding the contents or creation of the
document. Although questioned document examination most commonly includes the
examination and comparison of handwriting and signatures, the scope is not limited
exclusively to these parameters (Hilton, 1992). Document examiners investigate disputed
documents of which some of the most common may include cheques, letters, credit card
receipts, motor drivers’ licences, wills, contracts, suicide notes, anonymous letters, insurance
claim forms, passports, petitions, lottery tickets and medical prescriptions.
Forensic document examination includes two particular categories for most examiners. The
examination and comparison of handwriting, hand printing and signatures is one specific
domain and involves the comparison of questioned writing with samples of writing that are
known or purported to have been written by an identified individual. At the completion of
the examination the document examiner provides an opinion on the authorship of the
questioned writing based on the identifying features.
The second broader category of document examination relates to the physical examination
of the questioned document. Physical aspects of the document may include paper,
watermarks, erasures, obliterations, impressions, tears, and ink and toner applications.
Macroscopic and microscopic examination, aided by the application of light and filters, can
assist in the provision of vital information regarding the document’s origin and other
questions likely to concern an investigator or the court.
34
Forensic document examination is a diverse field and includes the following functions.
o Comparison of questioned signatures with known signatureso Mechanical impression comparison (typewriters, printers, rubber stamps, seals)o Visualising impressions in papero Identification of photocopy machineso Typewriter identification (make, model)o Non-destructive ink-examinationo Restoration of water or fire damaged documentso Physical matching of torn and cut papero Identification of printing processeso Graffiti and spray painting comparison
A physical examination of submitted evidence, within a holistic forensic document
examination procedure, involves thorough and meticulous scrutiny of documents. Examiners
may assess the surface features of the document for physical evidence such as alterations,
obliterations, indented writing, watermarks, security fibres, torn edges, moisture absorption
or fire damage.
In undertaking physical examinations, a number of different non-destructive techniques are
universally employed by forensic document examiners. Placing paper over a transmitted light
source will allow the examiner to determine the presence of a watermark. This may assist in
establishing the date period when the document was created. A document dated in 1978 on
paper bearing a watermark that was not produced before 1984 would obviously arouse
suspicion regarding the authenticity of the document. Other instruments and techniques,
such as electrostatic detection to visualise indented writing in paper, are also commonly
relied on. The ESDA (electrostatic detection apparatus) can be used to produce a visible
image of writing impressions in sheets of paper that were physically beneath a document at
the time it was being written.
The ESDA is the focus of the physical document examination part of the current study
detailed in this thesis. A recent innovation, the ESDAtesta, has been trialled and tested with
various types and weights of paper to establish its effectiveness and reliability for producing
robust images of impressed handwriting under various changes in the physical state of paper
both prior and post indentation (Steward, 1999). Factors such as changes in humidity,
35
pressure, number of sheets of paper beneath the writing surface and ability to produce
readable images following different degrees of oxidation (degrees of burning), have been
tested.
1.5.5 Project Scope and Objectives
The research detailed in this thesis was designed to address ink, pencil and paper chemical
analysis protocols to develop where possible additional unique analytical techniques which
could be used to determine uniqueness and provenance of the materials involved. In
addition, ESDA was applied to the determination of the limits to which the technique could
be applied to enhance and determine the nature of marks and indentations on “carbonized”
paper, an application thus far not investigated in the literature.
The primary objectives of this project were to:
• Test the boundaries and parameters for the physical examination of paper using the
Electrostatic Detection Apparatus (ESDA), a forensic device to detect indentations in
paper
• Chemical examination of paper to determine if the trace element distribution
patterns vary between different manufacturers but are stable within a single batch
• Chemical examination of ink to determine if the trace element distribution patterns
vary between different manufacturers but are stable within a single batch
• Chemical examination of ink on paper to determine whether trace element
concentrations for ink and paper can be determined separately
• Chemical analysis of pencil “leads” to determine if the trace element distribution
patterns vary between different manufacturers but are stable within a single batch.
The investigation detailed in this thesis was designed to investigate whether currently
existing ESDA protocols could be modified or extended to identify a wider range of marks on
paper. The study particularly concentrated on whether it was possible to use ESDA
techniques to clarify marks on charred paper. In addition, the use of ESDA techniques, in
association with modern chemical analytical protocols, was also investigated. This aspect of
36
the research was designed to try and establish if it was possible to use trace element
distributing patterns (fingerprints) to identify either generic chemical fingerprints for paper,
pencils and inks (both ballpoint and fountain pen) which would either relate these products
back to country of origin, manufacturer or, in the best case scenario, could be used to
establish a unique manufacturer or product batch, and whether it was possible to relate the
chemical fingerprint f charred paper back to the original uncharred material.
37
Chapter 2: Physical Methods: Electro Static Detection Apparatus (ESDA)
2.1 Introduction
One of many instruments that is commonly employed by document examiners world-wide is
the Electrostatic Detection Apparatus (Figure 2.1), also referred to as ESDA (Steward 1999),
manufactured by Foster and Freeman Ltd. (Vale Park Evesham Worcestershire WR11 1TD
UK). This equipment, which has been one of the most important scientific advancements in
the field of forensic questioned document examination, is used to detect and visualize
indentations on paper (Moore 1988).
Figure 2.1 The ESDA Instrument
Since it was first developed and introduced as a device for detecting indented impressions on
paper in England in 1978, the role and operation of ESDA in Forensic Science has been
extensively studied and researched by scholars and forensic scientists. The first study on the
ESDA was published in 1979 in the Forensic Science International. Written by Foster and
Morantz, it outlined the technical procedure of the ESDA and recognized that the relationship
between the charge density on the surface of cellophane film on the earthed metal plate and
the potential at its surface is given by the formula.
V = L ơ
KЄ0
38
where ơ is the surface charge density, K the dielectric constant, L the thickness of the
material and Є0 the permittivity of free space. In 1980, Ellen et al. also published an article on
the use of electrostatic imaging in the detection of indented impressions in the same journal.
They set out the operation of the ESDA and also highlighted its advantages in the field of
forensic science. However, in neither of these two original papers was there any mention of
the underlying mechanisms that effect the ESDA’s operation, such as the optimum conditions
required for examination.
Based on the principle that when writing is produced on a piece of paper resting on other
pages, impressions of the writing may be indented into the sheets underneath, it is these
latent writing impressions on the underlying pages, which may be invisible to the naked eye,
that can be recovered and made into permanent recordings using the ESDA process. ESDA
works by creating an invisible electrostatic image of indented writing which is then visualised
and recorded by employing a toning procedure (Ellen et al., 1980). The use of ESDA has been
perfected in forensic science to the point that an impression of the original document can be
traced to a depth of up to seven underlying sheets. In the application of ESDA, the latent
writing impressions left on the paper can provide vital and clear evidence for a variety of
investigations, both criminal and civil. For over two decades ESDA has been used
internationally as an instrument of necessity within Forensic Document Examiner’s
laboratories.
2.2 The Analytical Operation of ESDA
Similar to a photocopier, ESDA works by making use of an electrostatic imaging process. The
process creates an invisible electrostatic image of indented writing, which is then visualised
following the application of charge sensitive toners. The sensitive imaging process reacts to
small areas of microscopic damage to the fibres at the surface of the document, which have
been created through rough interaction with overlying paper surfaces during the act of
handwriting.
39
The ESDA consists of a 9.5 by 16.5 inch sintered bronze plate, a vacuum pump, black
photocopier toner, cellophane imaging film, adhesive fixing film, developer glass beads a
scalpel blade and circuitry for the high voltage required to create an electrostatic charge.
However, it has been found that if optimum results from the ESDA are to be achieved, then in
some circumstances the pre-imaging technique of humidifying the document must be
employed.
2.3 Pre- Imaging Technique. Humidifying
In 1981 at the 39th Annual Conference of the American Society of Questioned Document
Examiners in Houston Texas, a paper on ESDA was presented and, for the first time, the
forensic benefits of the ESDA instrumentation were internationally recognised. The work was
subsequently published (Baier, 1983). This paper which investigated and discussed
experimental pre-imaging procedures was the first to acknowledge the possible effect of the
moisture content of a document on the ESDA results. It recognised and highlighted the
requirement of humidifying the document as a pre-imaging technique that potentially
improved ESDA results.
Additional studies have indicated that ESDA produced the most effective results from
documents that were conditioned in a humidity chamber at 40 to 70 % relative humidity
prior to being examined by the ESDA. It has been found that, where documents were left
within the humidity chamber for extended periods of time, even as short as thirty minutes,
deleterious change could occur to some documents rendering the ability of ESDA to be used
to determine indented images being significantly reduced. For optimum results, it has been
established that document examiners should refrain from keeping documents within the
humidity chamber for longer than the fifteen minutes period that is recommended (Moore,
1987, Riebling and Koubs, 1994). Some studies have even suggested that the document
should only be kept in the ESDA humidifier for approximately five minutes (Heath, 1983). This
time period is also recommended in the ESDA manufacturer’s instruction booklet. However,
it should be noted that the standard humidifying time may need to be adjusted depending on
40
the prevailing humidity conditions within a laboratory environment in the first place and
during document storage before examination.
2.4 ESDA Operating Procedures
The ESDA has been designed as a manual system to allow the Document Examiner the
flexibility and freedom to deal with the wide range of materials encountered operationally.
Operating procedures are essentially similar for all paper samples and can be represented by
a series of logical procedures.
1) The document with the assumed latent indentations is placed face-up on an earthed
porous bronze plate, which has its underside connected to a vacuum pump. A thin
sheet of cellophane film is placed on top of the paper and the vacuum switched on.
With the pump in operation, a thin sheet of insulating cellophane film is then placed
over the full surface of the vacuum plate. This non-porous insulating film (upon which
the image is later developed) is drawn into firm contact with the vacuum plate,
sandwiching the document between the plate and the film. The cellophane covering
also serves to prevent damage to the original document.
2) The insulating film is then electrostatically charged by moving a thin corona wire at a
potential of 8kV across the surface (Figure 2.2). Static electricity discharges itself to
earth through the compacted paper and cellophane film and this differentially
charges the surface of the cellophane. The corona discharge unit is passed slowly over
the document three to four times to charge the surface, and in doing so forms the
latent images of the indentations present. The local capacitance, over the various
areas of the film and document sandwich, changes as a result of indentations in the
paper, thus causing fluctuations in the potential on the surface of the film.
3) These fluctuations constitute a stable potential image owing to the negligible leakage
of charge from the insulating layer. At this stage, the surface of the paper causes a
different pattern of charging in those areas where there are indentations, even at a
41
microscopic level. This difference results in an electrostatic image of the indentations
being created on the sheet of film.
Development of a visible image is achieved by lifting the vacuum bed to an angle and
applying cascade black toner over the cellophane sheet as shown in (Figure 2.3). This is done
by using glass beads (diameter 0.5mm) coated with ultra-fine black carbon powder as the
carrier of the fine black carbon toner (Foster and Freeman Ltd.). A collection tray on the side
of the equipment recovers the cascade developer beads for further use after they are poured
over the tilted vacuum bed. This application of the toner is repeated several times until a
satisfactory image is obtained.
Alternatively the toner may be applied by an aerosol process of misting, which involves a
misting cloud chamber being placed over the document. Similar results are obtained with
both development processes, although occasionally greater contrast results can be produced
with the cascade system.
Figure 2.3 The application of cascade toner over the surface of the film
Figure 2.2 Electrostatic charge. Corona discharge unit is used to charge the surface and from latent images of the present indentations (Foster and Freeman Ltd.)
42
The toner is strongly attracted to the electrostatically charged document and film and is
retained on the film surface in accordance with the amount of static charge present at any
given surface point. The parts of the document containing the higher static electric charge
retain greater portions of the black toner, resulting in a visible deposit of toner aligned with
the indentations on the paper. This implies that the indentations produce regions of lower
(i.e. more positive) potential on the charged insulating film. Thus, the negatively charged
toner is being repelled from the high negatively charged background and only adheres to the
more positive areas above the indentations.
Despite the apparent simplicity of the ESDA, there has been much debate over the principle
behind its operation. Some studies have indicated that it is the compression in the paper
surface that creates a positive surface charge which is detectable by ESDA (Wanxiang and
Xiaoling, 1988). However, more recently it has been suggested and experimentally proven
that the electrostatic effect of indented writing, as the creation of surface charge, is as a
result of friction. Through experimental evidence it has been shown that it is the friction
between the paper fibres that is responsible for creating sites at which positive ions from the
atmosphere can bond to the paper. Other indentations created by frictionless compressions
have been shown not to create an electric perturbation and have no noticeable effect in
ESDA. Further, compressions without friction have had no noticeable effect in ESDA also. This
suggests that ESDA detectable impressions can be transferred as the result of a wide variety
of contact mechanisms and not only be the act of writing. These findings have been
confirmed by Dines (1998), who demonstrated unequivocally that the ESDA detectable
writing impressions can be created in paper simply by contact with the reverse of paper
bearing heavy pressure writing which embosses the back significantly. It is on these principle
findings that the ESDAtesta is based, as by drawing the carriage and weight across and down
the top layer of paper; impressions are made in the paper underneath through the lateral
relative motion of the sheets.
2.5 Preservation of the Indentations
If the results are required for record, the powder image can be developed and preserved.
This is done by placing a protective transparent adhesive covering film over the top of the
43
cellophane film while it is still being held in place by the vacuum of the ESDA. This effectively
preserves the image of the indentations.
The resulting combined protective and cellophane films can be peeled away from the
document to produce a permanent full size transparency of the indentations, and also leave
an undamaged and uncontaminated specimen (document) which can be re-examined by this
or any other method as required. The resulting image is in the form of a series of black dots
that can form coherent images of indentations made by other documents on the paper. As
shown in Figure 2.4 Original Document (A) undergoes ESDA process to reveal the hidden
indentations (B) resulting in ESDA transparency (C). This can provide compelling and valuable
evidence in document examination. For example, if the recovered indented writing is of a
high enough quality, it may be used as evidence in associating a person with a questioned
document by comparing the handwriting indentations with standard material.
BA C

2.6 Potential Problems
One major parameter affecting the quality of ESDA results is the type of paper used. The
ability of ESDA to visualize indented writings varies greatly from one paper type to another.
Noblett and James, (1983) recognised this by examining ten different types of paper, ranging
from notepad paper to dual purpose ‘Xerox paper’, for indented writing under the ESDA. It
was found that thicker and better quality papers produced on average clearer and more
44
intense indented writings marks, when compared to fine grade and recycled papers such as
notepad and cotton paper. When several different types of paper are written on, creating
sets of indentations on a single underlying sheet, the additional thickness of the paper on top
does not interfere with the formation of ESDA developed images. However, if thicker and
heavier materials, as a top sheet, are written on then sheets of any thickness beneath them
would not be indented unless the pen pressure used was sufficient to overcome the
additional thickness (Lewis, 1981 and Moore, 1987). Similarly, paper type was also examined
as a variable that can adversely affect results produced by ESDA. In addition, it was found
(Lewis, 1981 and Moore, 1987) that poor quality and fine grade paper, such as type-writer
paper, were more susceptible than other superior types of paper such as cheque book paper,
to the ESDA process. Thus, question document examiners acknowledge paper type is another
factor that can affect the quality of ESDA results.
2.7 Applications of ESDA in Forensic Science
2.7.1 Overview
Although in recent years there has been the advent of new recording technology, in today’s
world there is still a high level of dependence on the use of documentation. Paper evidence is
commonly encountered in diverse forensic and civil cases, such as cases of forgery, fraud,
extortion and kidnapping. As ESDA provides a method of detecting and permanently
recording latent writing impressions, it can offer very valuable evidence to document
examiners by producing significant information, such as telephone numbers, names and
dates that could otherwise not be visible after the removal of the actual sheet on which the
original impressions had been made. Further, as ESDA can recover latent writing impressions
without damaging or destroying the document, its use is practical in forensic science as it
produces evidence whilst preserving the document in its natural form. Thus, due to its
flexibility in application and its non-destructive nature, ESDA is commonly used for the
following types of document examination and investigation:
• Source of identification in anonymous note cases;
45
• Record tampering/ alterations; (medical records, company files, cheques, wills, police
interview notes etc.);
• Recovery of information, such as names, telephone numbers etc.;
• The linking of apparently unconnected documents;
• Determining writing sequence (sequence in which a series of pages were written or
when they were written);
• Evidence in connecting someone to a questioned document (handwriting
recognition);
• Differentiating between primary and secondary markings.
ESDA is immensely advantageous in that it can be used to provide fresh compelling evidence
in a variety of situations involving document examination.
The technique is extremely sensitive, in that it can be used to recover very shallow
indentations which could not otherwise be easily or clearly reproduced. ESDA is so sensitive;
that it can even recover microscopic indentations which may be present several pages below
the original writing. Due to this advantage, ESDA can be used to provide evidence from
documents where no indentations are visible or where weak unreadable indentations could
only be identified. ESDA is also relatively simple to operate when compared to the alternative
technique of oblique lighting. This makes ESDA more practical and valuable, as both the time
and energy of forensic document examiners can be saved and made more efficient. Given
that within several minutes, results of any latent indented writing on a document can be
reproduced on a transparency with clarity, ESDA is both advantageous and practical to use.
ESDA is advantageous in that it records only the indented writing, ignoring the visible written
script on the document. ESDA treats the top copy of writing on the paper surface in the
opposite way to the indentations and in some way is similar to the old fashioned
photographic process where negatives and positives are involved. As the original document
(Figure 2.5A-B) undergoes the ESDA process, the hidden indentations are exposed on the
cellophane film (Figure 2.6). As the tonal image of any original writing on the paper being
tested is reversed, the original writing on the paper surface appears as red images on a light
grey transparent background (Figure 2.5A). The latent writing impressions are also recorded,
46
but as black writing against a light grey transparent background (Figure 2.5B). This is because
when the ESDA is used, the inked surface of the writing has the reverse effect on both the
electrostatic properties of the paper and also on the indented impressions. This difference in
the imaging record of any original writing and the indented writing makes it comparatively
easy to differentiate between the two and to decipher the suspected indentations, even
when the two overlap (Lewis, 1981). This is particularly advantageous, as most documents
which contain latent impressions which are important for forensic science purposes have
already been written on.

Figure 2.5A and 2.5B The black words are of the latent impressions, with the original writing appearing as red text.
The final product is a permanent transparency with a high precision and clarity (Figure 2.7).
The transparency, which holds a copy of the latent impressions in black, can then be placed
over a white surface and easily deciphered by anyone. Thus, even if the latent impressions
are in another language, a transparency copy can be given to one or a number of different
interpreters. Further as the latent impressions are recorded on a clear transparency, they can
be easily compared. For obvious reasons the clarity of the image produced by the ESDA
technique is also of value, especially when findings are of legal or criminal importance.
Finally, a typed copy of the results can be made for comparison with the original and
presentation as a support document to a jury and judge (Figure 2.7).
47
ESDA is non-destructive in nature. As the indentations are revealed on the protective
cellophane film, the original document remains unharmed throughout the process. Thus, the
original document can be further examined for other forensic evidence using other
techniques and instruments. The transparency result of the ESDA is detailed in (Figure 2.8). In
addition, fingerprints that could provide evidence to match to the suspects are also
highlighted. Given these advantages, the benefits of using ESDA in Document Examination
have become apparent and scientifically recognised.

2.7.2 Comparisons with Other Techniques
The practical advantages of ESDA also become more apparent when compared to other
techniques for the detection of impressions in paper. Historically there have been various
other methods employed. However, today, the ESDA is one of two techniques that are most
commonly used for the recovery of latent writing impressions, the other being oblique light
photography.
When a document bearing impressions is illuminated by a light directed obliquely across the
page, then the impressions are revealed by the shadow they cast. Photography in oblique
light consists of illuminating the document to be analysed in a dark room, by a light source
almost parallel to its surface, or at a slight angle of approximately twenty degrees. The
method shows up unevenness in the surface of the document, and any indentations or raised
areas on the surface give rise to shadows, thus enabling visualisation of the indentations. The
revealed impressions are then photographed for analysis.
Although this method is quite acceptable and like the ESDA is non-destructive, it has several
drawbacks when compared to the ESDA. Firstly, oblique light photography techniques are
often unable to recover non- visible microscopic indentations, which may have occurred
three or four pages down in a series of sheets or in a writing pad. Secondly, they also have an
inherently lengthy processing time as any impressions found have to be photographed and
then a second photograph at a different light angle must also be taken to illustrate the
difference between any different writing strokes. Whilst ESDA results can produce results
within a few minutes, oblique light photography can take over an hour to produce similar
results. Further, photographing a document by this method is difficult as the document must
be perfectly flat, as any raised areas create shadows and may obliterate sections of the
writing. Finally, the success of this technique largely depends on the skill of the forensic
document examiner in interpreting various fragments and thus results by this method are not
always consistent. Given these shortcomings, ESDA when available has become a more
preferred and practical approach in questioned document examination.

2.8 The ESDA Testa
2.8.1 Introduction
The ESDA has had, until recently, very few modifications since its first commercial production
in the late 1970’s. Recently, an updated model of the ESDA was released by Foster and
Freeman manufacturers. Known as the ESDA2 it provided for documents up to A3 in size and
replaced the cascade developers used in the image development process with a toner pad.
Further the ESDA2 comes equipped with a document humidifier, shown in (Figure 2.9).
Besides these few changes, the actual ESDA apparatus has remained virtually unchanged for
over thirty years and as such the technology has only been subjected to limited validation
protocols. However, with increasing quality assurance programs being required to be
implemented by police forces internationally in response to demands for forensic laboratory
international accreditation, there has been considerable pressure to devise some method to
accurately compare ESDA instrumentation internationally.
Recently one of the agents for ESDA in Australia, XTEK released the ESDAtesta kit (Figure
2.10), a new device designed to allow regular quality assurance, inter comparison and testing
of ESDA machines internationally. This equipment has been designed to test whether an
Figure 2.9 The new ESDA2 document humidifier
50
ESDA machine is working accurately for document examination purposes. ESDAtesta can
provide an ongoing record of any ESDA instrument’s calibration and thus offer proof to
validate any forensic evidence found whilst using the ESDA machine. Given the high level of
dependency on evidence produced by ESDA for Document Examination purposes; the
ESDAtesta can have important implications on the accuracy of such findings.
2.8.2 Analytical Operation of the ESDAtesta
The ESDAtesta is a device that allows for ongoing assurance and record of the ESDA
instrument’s calibration. Manufactured in Australia by XTEK Pty Ltd the ESDAtesta Kit consists
of. a carriage, stylus, five different weights, a drawbar, an Allen key, 3.5 inch floppy disk
containing reserve documentation, and ESDAtesta calibration forms. The components of the
apparatus contained in the ESDAtesta Kit are detailed in Figure 2.10. The QA template sheet,
although not shown in this figure, is shown in Figure 2.11A and these sheets are supplied by
XTEK Pty Ltd.
The ESDAtesta is designed as a manual system so that test indentations can be repeated on
different occasions. The ESDAtesta can either be used on a periodic basis or before the
analysis of case evidence by the ESDA. Furthermore, the ESDAtesta operates independently
from the operator’s input.
Figure 2.10 Diagram of the ESDAtesta components (XTEK LTD.)
51
The ESDAtesta calibration sheets are comprised of three QA (Quality assurance) sheets
attached together.
• The top sheet is referred to as the “QA Top sheet”. A carbon stock sheet.
• The middle sheet is referred to as the “QA Template”.
• The bottom sheet is referred to as the “Sample Sheet”.
The ESDAtesta calibration sheets comes with printed template of the lines marked ‘1 to 5’
horizontally and vertically, which corresponds to the weight used to indent the sheets
(Error! Reference source not found.
The three ESDAtesta calibration sheets are placed on a hard surface (
Figure 2A). The “QA Top sheet” is made of carbon stock, whereas the other underling two
sheets consist of 80 gsm printer/ photocopy paper. The ESDAtesta instrument is assembled
52
on a flat surface, with one weight on the stylus which is then placed on the carriage (
Figure 2B). The ESDAtesta is designed in such a way that the stylus ball protrudes below the
level of the carriage rollers and a constant weight on the stylus is maintained. The drawbar is
then hooked into the carriage (Figure 2.11B). The carriage with a single weight on it is drawn
across the ESDAtesta calibration sheets “QA Top sheet” horizontally above the lines marked
‘1’ which corresponds to the weight. This procedure is then repeated vertically. The
drawbar is employed when doing this, so as to prevent any external downward
pressure on the ESDAtesta stylus. The carriage is then lifted off the sheets, and one
more weight is added to the stylus. The carriage is then drawn across by the drawbar both
horizontally and vertically above the lines marked ‘2’ (Figure 2.11D). This process is
repeated, adding one more weight each time for lines ‘3’ through to ‘5’ with the
corresponding weight.
The “QA Top sheet” is then discarded. The middle sheet, the white “QA Template” sheet, is
then filled in by the examiner to record the details of experiment, such as the date and
53
experiment number, while the third sheet, the “Sample Sheet” that holds the indentations, is
the one imaged by the ESDA.
The last sheet, the “Sample Sheet” is then placed in an ESDA Humidifier so that it is suitable
for examination. The new ESDA2 humidifier, recommended for this procedure, is shown in
(Figure 2.9), although a humidity chamber may also be used. The manufacturer XTEK Pty Ltd,
in their instructions recommend humidifying the Sample Sheet for a standard ten minutes
when using the ESDA so as to produce identical conditions for the quality assurance test
every time and so as to be independent of the methodology needed in actual casework.
However, communications between the company and Sergeant J. Hansen (West Australian
Police Service; Forensics, Document Examination Division (personal communication)), have
indicated that a two-minute period of humidification is more appropriate. This time has
therefore been used in studies throughout this thesis.

2.9 ESDA Examination
A normal ESDA examination is then performed on the paper until a satisfactory result is
obtained as explained in Section 2.4. The sample page is also signed and dated, and together
with the template page they are attached to the fixed developed film from the ESDA, and
preserved for examination and comparison.
2.9.1 Overview
ESDA is a widely accepted and routinely used instrumental procedure for investigating latent
marks on paper (Moore, 1987). As such it is indispensable to document examiners. However,
specific limits of the ESDA instrumentation, especially the newest instruments, have not been
investigated fully. The purpose of this Section is to establish the detection limits of ESDA and

try to determine whether it can be used to recover marks on paper that has been heated or
even burned. Experimentation centred on the effect of changing paper types and the degree
of humidification of these papers together with heating paper to various temperatures to
simulate burning as a means of destroying material. The parameters investigated were:
• Variable 1 Paper Type
• Variable 2 Effect of Humidification
• Variable 3 Effect of high Temperatures
These three variables were manipulated and evaluated during a testing process in an attempt
to determine their relative impact, if any, on the efficiency of the ESDA instrument. The
various types and thicknesses of paper that were tested are listed in Table 2.2. Nine sheets of
each type of paper were used. Each paper type was selected so as to fairly represent the
variety of papers encountered by document examiners.

2.9.2 Experimental Procedure
Each of these six paper types was given a Paper Number corresponding to the information
listed in Table 2.1. Using the disk from the ESDAtesta Kit, which contained templates of the
ESDAtesta grids corresponding to the QA Top Sheet as explained in Section 2.8. The QA-Top
Sheet (Section 2.8 Figure 2.11A) was printed with five horizontal, and five vertical lines on
each of nine sheets of each type of the six types of paper, giving a total of 54 study sheets of
paper for this experiment. During this procedure, the ESDAtesta carriage, with a single
specified weight on it, was drawn across a page both horizontally and vertically across the
line marked ‘1’ (corresponding to that specific weight mass), then, after adding a second
weight, the carriage is drawn across the line marked ‘2’ and so on until all five weights and
lines corresponding to their masses had been drawn. The 54 sheets resulting from this
experiment were uniquely labelled on each bottom corner.
Nine sets of sheets were created out of the six different types of paper and the testing
procedure was conducted in three separate phases (Table 2.2).
Table 2.2 Test Procedure Outline. Each set contains QA Top Sheet, Template Sheet and Sample Sheet.

2.9.2.1 Phase One. Paper type
In Phase one, the reliability of the latent indented lines produced by the ESDAtesta was
examined only in relation to the various paper types and qualities. In this phase ESDAtesta
was performed on each paper type three times for repeatability. Using the carriage from the
ESDAtesta kit lines was marked on a piece of paper at five different indent pressures, the
same indent pressures were used for each paper. This was conducted on one set of paper
from each of the six paper types. All five weights from the ESDAtesta Kit were used in the
experiment, followed by a standard ESDA test explained in Section 2.8 on the QA Sample
Sheet from each set, giving a total of nine ESDA transparencies as explained in Section 2.9.
The paper sets examined in this phase were tested at room humidity, and thus they were not
humidified in the humidifier chamber. The reason behind this was to examine the papers in
their natural state without trying to enhance the outcome of the ESDA results.
2.9.2.2 Phase Two. The effect of humidification
Routinely, documents in forensic science laboratories are placed in the ESDA humidity
chamber for periods of five to fifteen minutes, depending on the personal preference of the
individual examiner. The manufacturers of ESDAtesta, XTEK Pty Ltd, recommend in their
instructions a humidification of ten minutes. However, a memorandum released recently by
XTEK Pty Ltd to the Document Examination Section of the Western Australian Police Service
recommended that humidifying the document for two minutes was more appropriate. In
Phase Two, the effect of humidification on the latent indented lines produced by the
ESDAtesta procedure was examined. The reliability of the ESDA was studied in relation to the
different paper types being conditioned in the humidity chamber for a period of two minutes
prior to the ESDA procedure. Phase two, the effect of humidification, was conducted over a
three-day period and the ESDAtesta indented lines were performed on each paper type three
times for repeatability. The complete ESDAtesta procedure with two minutes of
humidification was conducted on sets D, E and F from each of the six paper types on each
consecutive day.
58
2.9.2.3 Phase Three. The effect of increased temperatures
In this phase ESDA was performed as explained in Section 2.4. The paper samples were
placed between two ceramic blocks with card board sheets surrounding them to act as
spacers between the bottom and top ceramic plate (Figure 2.12A). Under this configuration a
series of paper sheets could be built up between ceramic plates with cardboard spacers
between each in order to heat a series of paper samples individually under the same
conditions. The cardboard served to stop the increase of oxygen during heating and acted
somewhat like the pages of a book, which if thrown on a fire would limit complete oxidation
and promoted simple carbonization. Once assembled the paper was placed into a pre-heated
muffle furnace Figure 2.12B, and Figure 2.12C at a specific temperature and equilibrated for
60 minutes.
Three different temperatures were chosen, 200oC, 300oC and 400oC. At temperatures above
400oC the paper was completely carbonized and no indentations could be observed. In
addition, at this high temperature, the carbonized paper was so brittle that it could not be
transported satisfactorily to the ESDA instrument and certainly could not withstand the
flattening process required before treatment.

Once removed the paper sheets showed various degrees of heat treatment and colour changes
with samples heated to 400oC being almost completely carbonized (Figure 2.13A-C). Following
heat treatment all samples were investigated for the presence of the marks ruled on them
using ESDA (Figure 2.14).
2.9.3 Analytical Methods
As the ESDAtesta weights and carriage were drawn along the different sets of paper in both
directions, it was expected that they would create a latent indented line on the pages below
Thus when the ESDA was used on each sample sheet, it highlighted the marks and they were
then able to be recorded, interpreted and kept. The ESDA transparency records from Phase
One, Two, and Three were evaluated based on the precision and clarity of the line produced.
In order to evaluate the variables tested, the clarity of the visualised indented lines resulting
from the five weights were assigned a point value. If the indented line produced was dark,
and clearly defined it scored two points. If some of the line was rendered visible but
somewhat vague in some areas, it scored one point, and if no line was observed a score of
61
zero points was ascribed to the “mark”. This point system was applied to both the horizontal
and vertical indented line produced as a result of a line being drawn under the pressure of
each weight. Thus for example, a transparency that showed visible and clear lines on all five
weight levels both horizontally and vertically would be scored the maximum of twenty points,
2 points for each line. Whereas a transparency that showed two visible but imprecise
indented lines, and no visualizations on any of the remaining eight lines, received a score of
two.
A total of 54 paper samples from six different paper types representing 18 papers from each
of the three phases of the experiment, namely the paper type, the effect of humidification
and the effect of heat, were tested using the ESDA. The results were analysed according to
this point system.
2.10 Results and Discussions
Phase one results, where only the paper type was variable, are summarised in Tables 2.3 to
2.8, phase two findings, which correspond to the variations in humidification, are detailed in
Tables 2.9 to 2.14, and phase three results, where high temperatures were the only variable,
are summarised in Tables 2.15 to 2.20. In all of these tables, “H” refers to horizontal indented
lines and “V” to vertically indented lines created by the ESDATesta carriage. In assigning the
point values for analysis, all eighteen underlying QA sample sheets were examined.

2.10.4 Discussion of Results from Phase One Experiments
The research results from Phase one indicated that the strongest ESDAtesta indented results
were obtained with the heavier grades of paper, 100 and especially 110 gsm. In contrast,
when the notepad paper which is of low quality and finer in composition was tested, the
results showed that the ESDAtesta indentations were weakly produced. Document evidence
typically involves the examination of sheets of standard printer paper, which generally have a
unit mass of 80gsm. The results from the Blue Printer Paper (paper type 6) were consistent
with the results from paper type 2 (80gsm), suggesting that although the Blue Printer Paper
was dyed blue its fibre composition was the same as the normal white photo copy paper.
The blue dye in the paper had no substantial effect on the results obtained in this phase of
the experiment as it was not expected to have affected the paper fibres in any significant
way. The results presented in this paper are consistent with other studies (Riebeling and
Kobus 1994), in that they demonstrate the importance of paper quality in the detection of
latent imprints using ESDA.
As was expected, the quality of paper was also an important factor governing the ESDAtesta
process. This is because indentations in paper that are detectable by ESDA are transferred
through the paper as a result of friction between the paper’s fibres in the top and lower
sheets. When the ESDAtesta process is conducted on heavier grades of paper, the higher
quality fibres in the paper generate more friction between each other and as a result the
ESDAtesta indentations are more readily produced.
The data presented clearly demonstrate that if the ESDAtesta is to provide quality assurances
of the ESDA for casework and evidence verification, then the paper type on which the
ESDAtesta is tested must correspond to the paper quality of the document being tested by
the ESDA. Further if the ESDAtesta is to be used regularly to quality assure the ESDA in any
laboratory, document examiners must routinely perform the ESDAtesta process on the
variety of paper types encountered in document examination in order to adequately
familiarise themselves with the effect of paper quality on results.
68
2.10.5 Discussion of Results from Phase Two Experiments
The research results from Phase two were not as consistent as those in Phase one. As
humidification increases the moisture content of a document, it was expected that this would
produce better quality ESDAtesta indentations and that the point value averages in Phase
two of this experiment would increase from those in Phase one.
However, it was found that humidifying the document for two minutes produced poor and
inconsistent results. With all the six paper types, humidification of the document prior to the
ESDA process weakened the visibility of the latent impressions from the ESDAtesta. The
Phase two point value averages which all decreased when compared to the results from
Phase one are shown in Table 2.22. The results are inconsistent and a trend between the
effect of humidification and paper type on the ESDAtesta results could not be established.
Whilst these results contradict earlier published data on the effect of humidification on ESDA,
they indicate that the ESDAtesta process is extremely sensitive and that the indentations
produced are consistently lower than for the equivalent dry material when paper is
humidified. These results appear to suggest that humidifying the document, for even as short
as two minutes can adversely affect the development of latent ESDAtesta indentations. As
this part of the study was restricted to the effect of humidification for only two minutes a
conclusive rationale for the results cannot be given. One possible rationale could be that as
the paper documents were not left at room humidity for an extended period of time and
therefore were not ‘dry’ so as to need humidification, the humidity chamber had the effect of
overexposing the paper to water vapour and thus produced less quality results. However,
without further research, such a rationale cannot be definite; research findings simply
indicate that humidification on the ESDAtesta process can affect the outcome of results.
2.10.6 Discussion of Results from Phase Three Experiments
The research results from Phase Three were more consistent than those in Phase Two and
were as good if not better than those of equivalent paper that had not been heated. This was
surprising because heating decreases the moisture content of a document, and it was
expected that in this phase heating to high temperature would produce lower quality
69
indentations. Nonetheless investigations were able to prove that even when the paper was
heated up to 300oC it was still possible to develop the marks and it was only after the paper
was almost charred at 400oC that the ability to develop the indentations further was lost and
this largely due to the fact that the paper was so brittle that it was not possible to lay the
paper on the ESDA instrument.

The scenario was trying to mimic the possible disposal of a document by setting fire to it, or
throwing it on a fire, but the fire not completely destroying the document, if the imprint
would still be there. It was envisaged that the point value averages in Phase Three of this
experiment would increase from those in Phase One. However, it was found that applying
very high heating (4000C) to the (6 types) of paper, no visible lines were produced.
With all the six paper types, heating of the document in a (2000C and 3000C) in oven prior to
the ESDA process strengthened the visibility of the latent impressions from the ESDAtesta
over the data for equivalent paper heated to 400oC. Direct comparisons of results are
detailed in Tables 2.17-19. The results from paper (type 3-5) samples (3G, 3H), (4G, 4H), and
(5G, 5H) which were exposed to heat (2000C and 3000C) indicate that these papers with
higher gsm masses (90, 100, and 110gsm) showed more consistent results than those for
paper (type 1, 2, 6) as shown in (Tables 2.15, 2.16, and 2.20). Paper (type 1, 2, 6) in Tables
2.15, 2.16, and 2.20 have lower gsm (80, and 90). This demonstrates the importance of paper
quality in the detection of latent imprints by the ESDA. Results for samples (6I) from the (6
types) of paper that were exposed to (4000C), indicate that no indentation was recoverable.
70
The high heat charred most of the document and on the part of the document which did not
get charred there was no visible line to record after the ESDA technique was applied.

3.1 Analytical Methods
3.1.1 Instrumentation
Three analytical techniques were used throughout this research; Inductively Coupled Plasma
Atomic Emission Spectroscopy (ICP-AES), Inductively Coupled Plasma Mass Spectrometry
(ICP-MS) and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). A
Thermo iCAP 6500 Inductively Coupled Plasma-Atomic Emission Spectrophotometer (ICP-
AES) (Thermo Fisher Scientific Australia Pty Ltd 5 Caribbean Drive, Scoresby Vic 3179) and an
Agilent 7700cs Inductively Coupled Plasma Mass Spectrometer (Agilent Technologies
Australia Pty Ltd, 679 Springvale Road, Mulgrave, Vic 3170), were used to produce all
analytical data. A New Wave UP-213 laser system (13900 NW Science Park Drive, Portland,
Oregon 97229-5497, USA) was used for all laser ablation experimentation. The use of laser
ablation allowed small areas of the sample to be analysed without the requirement to take
the bulk sample into solution.
Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) and Inductively Coupled
Plasma Mass Spectrometry (ICP-MS) are two common analytical techniques employed for the
determination of analytes at minor to ultra-trace concentrations in a wide variety of sample
types (Korsrud et al., 1985; Zhou et al., 1997; Mahan et al., 1998; Bush et al., 1995; Anan et
al., 2001; Ikemoto et al., 2004; Catarino et al., 2006; García-Ruiz et al., 2007; López-Alonso et
al., 2007; Ludwick et al., 2008; Linge, 2009; Nardi et al., 2009; Gerber et al., 2009; Watling et
al., 2010; Furia et al., 2011; López-Alonso et al., 2012). Due to the different sensitivities of the
two instruments, and to the different interferences that occur in each technique, the use of
both ICP-MS and ICP-AES in this research facilitated the determination of a wider range of
analytes and gave the highest levels of analytical accuracy by using the most appropriate
technique for each analyte. Consequently, the use of both techniques enables all analytes to
be determined using both the optimum analytical technique and also in the optimum
analytical range for their solution concentrations (Soltanpour et al., 1996; Linge and Jarvis,
2009).
72
Atomic Emission Spectroscopy (ICP-AES) has a sensitivity that is reduced by one to three
orders of magnitude compared to ICP-MS (Soltanpour et al., 1996; Luykx and van Ruth,
2008). However, analytes such as sodium, magnesium, calcium, potassium and aluminium,
which are relatively high in concentration in biological matrices (including paper) are difficult
to quantify using ICP-MS due to significant complex-ion isobaric-overlaps. These analytes
however are much more accurately determined at trace and minor concentrations using ICP-
AES.
In addition to the basic instrumentation, LA-ICP-MS was also employed. The use of laser
ablation allowed small areas of the sample to be analysed without the requirement to take
the entire sample into solution. In addition, by using the line ablation protocol for LA-ICP-MS,
it was possible to determine variations in elemental patterns across the surface of paper
samples and also to produce data for scanning across the interface between blank paper and
paper that had been written on, by traversing the ink/paper interface.
All solution-based analytical data (generated using ICP-AES) were quantified with reference
to in-house standards made by serial dilution of multi-element calibration standards from
Merck Chemicals™, Australia. These standards were analysed at the beginning and end of
each analytical run. A drift solution, consisting of a bulk solution of the sample type being
analysed, was introduced every twelfth sample of the analytical run. This approach was used
for both ICP-AES and ICP-MS analyses to ensure inter-run comparability of data. Rh and Ir
were also used as internal standards (2ngmL-1) for ICP-MS analyses to correct for both drift
and matrix effects in the samples and also to ensure inter-run comparability of data (Saitoh,
et al., 2002).
First developed in the 1980’s, solution based ICP-MS soon became the technique of choice,
firstly for geologically based analyses and then for a much wider range of materials, as the
technique exhibited far fewer interference problems than ICP-AES and was significantly faster
for the production of quantitative multi-element data than any other technique then, and
even now, available. Not only was ICP-MS more sensitive than earlier techniques, thus
facilitating the analysis of trace or ultra-trace level elements in a matrix (Lam et al., 1995;
Koppenaal et al., 2004; García-Ruiz et al., 2007; de Hoffman and Stroobant, 2007), the
73
instrumentation allowed for the rapid determination of multiple analytes almost
simultaneously with the
produced spectra being simple to interpret (Zhouand and Liu, 1997). Following its
development significant research into the technique has led to a wide variety of new
procedures and improvements which have made it one of the most powerful analytical
instruments available (Koppenaal et al., 2004; de Hoffman and Stroobant, 2007; Linge and
Jarvis, 2009).
3.1.2 Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES)
Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) is an analytical
technique that uses an inductively coupled argon plasma to generate excited atoms and ions
which, when returning to their ground or lesser excited state, emit electromagnetic radiation
characteristic of that specific element. The technique quantifies the emission intensity of
both ion and atom emission lines and relates these values to a standard-based calibration
curve for each analyte to quantify the relevant analyte concentration (Boumans, 1987).
For Atomic Emission Spectroscopy (AES), light emitted after the excitation of atoms using an
Inductively Coupled Plasma (ICP), is recorded by the detector (Soltanpour et al., 1996; Linge
and Jarvis, 2009). The energy provided by the plasma provides enough energy to excite the
atom temporarily into a higher energy level (Luykx and van Ruth, 2008). As the energy is lost,
and excited atoms return to their stable state, they emit light which is characteristic for each
quantum drop of the electrons and is therefore characteristic for each analyte (Skoog et al.,
1998; Skoog et al., 2007). The produced light is passed through an entrance slit of a
polychromator and focused onto a grating using a series of mirrors and lenses. To achieve
clear wavelength separation, modern polychromators are based around an Eschelle
polychromator system (Skoog et al., 2007). Once separated into component wavelengths, the
individual wavelengths of light pass through exit apertures in an aperture plate, and their
intensities are recorded as electrical signals using individual charge injection or charge
coupled devices as an electrical signal. This electrical signal is directly proportional to the
emission intensity of the individual spectral line, which, based on signals derived from the
74
intensities produced by equivalent analytes in standards, is in turn proportional to the
concentration of the relevant analyte in solution. Depending on the instrument, the
wavelengths of the different elements can either be detected sequentially or simultaneously
(Skoog et al., 2007). A diagrammatic representation of an ICP-AES is given in Figure 3.1.
Figure 3.1. Schematic of an Inductively Coupled Plasma Atomic Emission Spectrophotometer using an Eschelle grating. (Figure reproduced from Skoog et. al., 2007).
Although 19 elements, represented by 29 analytical wavelengths (Table 3.1), were
determined using ICP-AES only analytes relevant to the specific sample type being studied
were used for the determination of provenance of the individual sample types. The actual
analytes used in each study are detailed in all diagrams associated with the sample type and
are recorded in the relevant Appendices of this thesis. In order to avoid confusion, the
relevant analytes used for the specific sample type being discussed are specified individually
in each chapter. It is important that there is flexibility in the number and make-up of analytes
used in each study as the analytes vary in concentration (or CPS) with respect to each sample
type and provenance identification is compromised if analytes with roughly the same
concentrations in all the samples, or analytes that are at, or below, the detection limit of the
technique, are unnecessarily used in algorithms applied to the identification of sample origin.
Consequently, the number and make up of analytes used for provenance determination
varies between sample types.

Initially, as it was not possible to be specific as to the analytes that would assist in the
interpretation of data, as many analytes as possible and relevant were always determined.
Following analysis and preliminary data interpretation, a refined list of analytes was
developed for each sample type and data for some of the unreported analytes were used for
cross validation between ICP-MS and ICP-AES data to confirm reproducibility of the final data
and were not used in the final provenance determination investigation.
A Thermo Scientific iCAP 6500 series ICP spectrophotometer was used throughout this thesis.
Analytical solutions needed to be diluted in order to contain <2% Total Dissolved Solids (TDS).
Following dilution, quantization is achieved with reference to data for calibration standards
(0-100µgmL-1). These standards were supplied by AccuTrace™ (Registered trade mark of the
Dow Chemical Company, 2030 Dow Centre, Midland, Michegan, USA 48674), and were
diluted to the appropriate range using 18MegΩ resistance deionised water. Sub-boiling
redistilled nitric acid was produced using a quartz still (manufactured by Quarzglas
Komponenten und Services QCS GmbH, Germany) and each batch checked for purity before
use. Nitric acid was added to the final solution to give a final acid strength of 5% v/v after
dilution to the appropriate final volume. Analytical samples were diluted to an appropriate
final volume in the same manner.
3.1.3 Inductively Coupled Plasma as an Ionization Source
For the determination of elements using ICP-MS and ICP-AES the sample solution must first
be converted into an aerosol prior to being ionized (de Hoffman and Stroobant, 2007). In
both these instruments, the common ionization source is the Inductively Coupled Plasma
(ICP). Samples are nebulised to form a fine aerosol mist before introduction into the plasma
(Skoog et al., 1998; Skoog et al., 2007; de Hoffman and Stroobant, 2007; Linge and Jarvis,
76
2009). The nebulization system for both ICP-AES and ICP-MS are essentially the same and
consist of a nebulizer, usually based around a Meinhard™ design (Meinhard, 700 Corporate
Circle, Suite L, Golden, Colorado 80401-5636, USA) and a cyclone based spray chamber that
may or may not be cooled to temperatures between 10oC and 20oC. If the solutions being
aspirated are organic in nature the cooling water can be as low as 5oC. The nebulized sample
is introduced into a spray chamber where particles greater than approximately 2μm in
diameter are removed and drained to waste. The separated <2μm particle size aerosol is co-
entrained with the nebulization gas which enters the plasma through the innermost quartz
(nebulizer) tube of the plasma torch. The nebulised gas forces its way through the centre of
the plasma where it is first desolvated and the residual particulate material ionized with the
resulting ions passing through the sampler and skimmer cones (interface) into the mass
spectrometer.
3.1.4 Inductively Coupled Plasma Mass Spectrometry
The ionization system of the ICP (the plasma) is contained within the outer of three
concentric quartz tubes. A water cooled copper coil, which is wound around the outermost
quartz tube, supplies a magnetic field to the plasma and a radio frequency generator (RF)
produces an alternating current within the coil (Skoog et al., 1998; Skoog et al., 2007; Linge
and Jarvis, 2009). The plasma is produced following the initial electron-seeding of the argon
gas using a Tessla discharge. The resulting ions are controlled using a radiofrequency (RF)
field and further ion interactions ionize the argon gas resulting ultimately in the production of
an argon plasma with an electronic temperature of approximately 10,000oK (Soltanpour et.
al., 1996; de Hoffman and Stroobant, 2007). A diagrammatic representation of an ICP can be
seen in Figure 3.2.
Ionisation of the sample in the plasma results in the production of an ion beam, which is then
sampled from the plasma through a hole in a nickel or platinum sampler cone and a skimmer
cone made of the same material. Once through the skimmer cone the ions pass into the mass
spectrometer. The ions are then focused into a collimated beam using a series of ion lenses
and then passed into the quadrupole where they are separated on the basis of their mass to

charge ratio (m/z) prior to exiting the quadrupole and passing on to the ion multiplier for ion
magnification. Ultimately ion counts are recorded for quantification purposes (de Hoffman
and Stroobant, 2007; Linge and Jarvis, 2009). A range of different mass analysers including
ion trap, time-of-flight, quadrupole, and multi-collector systems exist to separate out such
ions (Koppenaal et al., 2004). Depending on the mass analyser used, the ions are sorted using
either an electric or magnetic field to control which ions reach the detector at a given time
(de Hoffman and Stroobant, 2007; Boyd et al., 2011; Linge and Jarvis, 2009). The sorted m/z
ions are then sent through to the detector where an electrical current, proportional to the
relative abundance of each ion, is produced from the incident ions. A data processing system
interprets this signal and produces either a mass spectrum of the sample (de Hoffman and
Stroobant, 2007; Boyd et al., 2011) or output of counts per second for each analyte detected
(Boyd et al., 2011; Linge and Jarvis, 2009). The concentration of the elements of interest can
be determined by comparing the electrical signal (counts per second (CPS)) produced for
each isotope ion in a sample with that for the equivalent isotope ion produced when
nebulising a reference sample or calibration standard. A diagrammatic representation of a
quadrupole ICP-MS is given in Figure 3.3.
ICP-MS was used in this thesis to determine the concentration of 52 elements (Tables 3.2 A-
D). Amongst this range of analytes there were a significant number that were considered to
either exhibit isobaric overlap interference problems (e.g. 51V, 52Cr, 53Cr, 75As, 77Se) or could
be used to correct data for those isotopes that had recognised isobaric overlap problems
78
(Tables 3.2 A and C). These isotopes were used to perform a series of corrections to achieve a
final list of analytes (isotopes) that could be used for provenance determination (Tables 3.2B
and D).

Although ICP-MS is an extremely sensitive analytical technique, which is traditionally used for
trace and ultra-trace analyte concentration quantitation, the technique can also be used to
provide concentrations for relatively high analyte levels (µgmL-1), as was the case with data
detailed in this thesis. Similarly to the data produced using ICP-AES, not all the analytes
determined using ICP-MS were directly used in data interpretation in this study. In some
cases, some analytes not directly reported in the text, were used for cross calibration and
data validation between ICP-AES and ICP-MS. In this way, any interferences occurring in a
specific technique could be easily identified and either corrected for or the most appropriate
analytical technique retrospectively chosen.
The ICP-MS instrument used was an Agilent 7500CS Inductively Coupled Plasma Mass
Spectrometer (Agilent Technologies, Inc., Santa Clara, CA, USA). The Standards used for the
calibration were obtained from AccuTrace™ (Registered trade mark for the Dow Chemical
Company, 2030 Dow Centre, Midland, Michegan, USA 48674). This series of ICP-MS
standards is provided as five different reference solutions (Icp-Ms-Cal-3.1, Icp-Ms-Cal-3.2,
Icp-Ms-Cal-3.3, Icp-Ms-Cal-3.4, Icp-Ms-Cal-3.5). The instrument calibration standards were
prepared by mixing the relevant standards (taking account of insolubility criteria) and diluting
them to the appropriate concentration using 18MegΩ resistance deionised water. The final
80
solutions were made to volume to contain 2% sub-boiling quartz-redistilled nitric acid.
Samples were made up to final volume before analysis to be <500 µgmL-1 TDS in solution also
using 2% sub-boiling quartz-redistilled nitric acid in which rhodium and iridium had been
added to give a final concentration in solution of 2ngmL-1. Rhodium and iridium were added
as internal standards to facilitate normalization of data in the event of drift during the
analytical run.
3.1.5 Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS)
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is a solid sample
introduction technique that provides rapid, multi-elemental, low detection limit analysis
facilitating chemical characterisation of samples as small as 10µm in diameter with minimal
sample destruction. In LA-ICP-MS protocols, a laser of specific wavelength is focused onto the
surface of a solid sample through a window in a quartz ablation cell (Trejos and Almirall,
2005). Most commonly, this involves the use of an Nd:YAG laser operating at a fundamental
wavelength of 1064nm. The instrumentation used in this study, makes use of frequency
modulation of this light to the fifth harmonic and operates using frequency quintupled
213nm wavelength light. The laser beam is focussed onto the surface of a sample at a chosen
point, where energy is transferred to the sample surface. Interaction between the beam and
sample surface results in the ablation of ultra-fine (nm to μm sized) particles (Günther and
Hattendorf, 2005). The resulting ‘ablated’ aerosol of debris is transported in an argon:helium
mixed carrier gas and directly introduced into the plasma. The finer the particle size, the
better the transport efficiency of the aerosol resulting in improved sensitivity.
The advantages of this technique are that it provides a means for multi-elemental analysis of
solid material which can be directly introduced into the plasma without having to
independently sample and dissolve the material first, which is particularly appropriate for
forensic samples that are microscopic in size, cannot easily be removed from a substrate or
are dissolution-resistant materials. LA-ICP-MS can also facilitate the provision of spatial
information by allowing analysis of small selected areas of the sample. In addition, sample
preparation procedures are effectively eliminated, ensuring that labour costs, solvent-
induced spectral interferences, volatile element loss, dilution errors, reagent contamination,
81
costs associated with reagents and sample transfer losses arising from sample handling steps
are all avoided, or at least minimized.
Figure 3.4 A An image of the UP 213 laser ablation system; B - A close up of the ablation cell with the laser (encased in orange plastic shield).
While Laser Ablation ICP-MS analysis provides the primary source of provenance
determination data for the ink on paper studies in this thesis (Section 4.5), all ballpoint and
fountain pen ink samples and all paper samples were analysed using solution based
techniques. Laser Ablation Inductively Coupled Plasma Mass Spectrometric analysis was
undertaken using a New Wave Research Co. Ltd. (Cambridgeshire, England) UPI 213nm Nd :
YAG laser system (Figures 3.4A and B) coupled with an Agilent 7500CS Inductively Coupled
Plasma Mass Spectrometer (Agilent Technologies, Inc., Santa Clara, CA, USA). The ICP-MS was tuned
prior to the commencement of each day’s analysis using a National Institute of Standards and
Technology (NIST) 612 glass standard. Throughout the analytical run, after every ten samples
the NIST 610 glass standard was analysed to facilitate normalisation of the data for
instrumental drift, correction for which, if necessary, was undertaken at the end of each
analytical run. The reason for using the two available NIST standards (NIST 610 and NIST 612),
was that when the ICP-MS is being tuned, continuous ablation of the standard occurs, a
process taking several minutes. Under these conditions if NIST 610 was used it would result in
the unnecessary introduction of ten times more analyte “contamination” into the mass
spectrometer as would occur if the lower concentration NIST 612 standard was used.
However, the use of NIST 610 standard for normalization makes use of the fact that the
higher concentrations of analytes present in this standard give rise to higher (CPS) signals
A B
82
which are more statistically significant when assessing instrumental drift throughout an
analytical run. Data for approximately ten seconds of instrumental gas blank were collected
prior to each analysis to allow for background correction.
The precision of data obtained as a result of LA-ICP-MS, is heavily dependent on laser-to-
sample coupling efficiency, changes in which can result in signal fluctuations caused by pulse-
to-pulse variations in the amount of sample ablated and hence the amount of analyte
reaching the plasma (van de Weijer et al., 1992). Consequently, LA-ICP-MS is still a
predominantly qualitative technique as there are no suitable matrix-matched standards
available for the majority of sample matrices and the heterogeneity of samples makes it
almost impossible to determine accurate bulk analyte concentrations. However, for the
analytical protocols used in this thesis, the qualitative nature of the analysis has no effect on
data interpretation. In this thesis the interpretation of data relies on the comparison of inter-
isotopic ratios as opposed to comparison of absolute concentration values (Watling, 1999).
Consequently, the data obtained using this analytical method are perfectly suited for the
provision of data that can provide information regarding the sample origin or ‘provenance’.
3.2 Data Analysis and Interpretation
3.2.1 Multi-Element Data Interpretation
Multi-element analysis facilitates the identification of a key set of variables, and their
relationships to one another. Such analysis can provide a characteristic pattern, or chemical
fingerprint, of a sample that can relate it back to its geographic region of origin,
manufacturing site or batch of manufacture (Kreitals and Watling, 2014; Valentin and
Watling, 2013; Martin et al., 2012; Watling et al., 2011; May and Watling, 2011; Watling et
al., 2010; Pilgrim et al., 2010; Luykx and van Ruth, 2008; Bartle and Watling, 2007; Watling et
al., 1999; Watling, 1998; Watling et al., 1993). However a visual comparison of multi-element
data in the form of a chemical fingerprint is only feasible for a small number of samples.
When the chemical profiles of samples become complex with an increased number of
variables being analysed, and the sample number becomes large, the differences between
chemical profiles of samples can become difficult to visually identify and discriminate
between (Watling et al., 2010).
83
Under these circumstances it is often required to reduce the data set to more manageable
proportions and to achieve this, a screening technique called “Comparability Index (CI)”
screening, has been employed. The Comparability Index (CI) statistics (Thomas et al., 1993)
are based around a sorting sub-routine that uses the logarithmic values of the CPS data, or
quantitative data, for a reference sample and compares these values with equivalent element
values in the remaining data base samples. These differences are then summed and sorted to
obtain an approximation of the relative comparability (fit) of the spectra of elements
(elemental fingerprints) for each sample, within the data set, to the reference sample
fingerprint. The series is sorted on the basis of a comparability index value which is the
difference from a 100% fit of the questioned sample with itself and as such sets a value for
the highest level of comparability (100%) possible. A 100% fit can only be achieved with
identical elemental fingerprints being compared. This is a statistically impossible situation in
any analytical regime and consequently only the use of the reference sample data (entered
twice) into the program ensures that a 100% fit is achieved. The 100% fit ensures that the
maximum possible comparability point is fixed in the interpretational protocol. The worse fit
of the questioned sample to one of the other samples in the database is designated as a 0%
comparability fit rating. Once comparability ranking has been achieved for all samples, it is
then also necessary to visually compare the spectral fingerprint of the high comparability
samples to the questioned sample to ensure that the fit is genuine and not an artifact based
on only statistics.
In addition to simply referring to the numbers (percentage comparability), it is also advisable
to plot the percentage comparability relative to the specific sample giving that comparability
and its positional number in the database. In this way significant changes in the slope of the
plot (“break in slope”) frequently can be observed, these breaks usually indicate the start of
new populations and are a means of sorting data. It is the samples with the highest %
comparability prior to the first break in slope that indicate which samples may be classified as
belonging to the same group as the reference sample. By using the CI, samples from the data
set may be tested to determine which of the other samples they share a high percentage of
similarities with. Comparability tests have been used previously in the literature to identify
unknown samples or to determine sample co-associations, especially with respect to the
84
forensic “fingerprinting” of samples (Watling et al., 1997, Green and Watling, 2007). Having
determined which samples have a significant degree of comparability (equivalent elemental
fingerprints) these samples are then removed from the data base and independently
subjected to more conventional statistical and chemometrical examination to confirm or
reject the preliminary interpretation.
Chemometrical analysis applies statistical interpretational procedures to the interpretation of
multiple variables. The application of these procedures, specifically related to the use of
Linear Discriminant Analysis (LDA) and Principal Component Analysis (PCA), has been
extensively applied specifically to the determination of provenance of foodstuffs (Watling et
al., 2010; Luykx and van Ruth, 2008, Valentin and Watling, 2013, Martin et al., 2012, Pilgrim
et al., 2010.), forensic evidence (Watling et al. 2011., May and Watling, 2009, May and
Watling, 2011), aboriginal artworks (Scadding et al., 2015) and animal distribution patterns
(Kreitals et al., 2014). As a result of increased computational capacity (Gnanadesikan, 1997),
chemometric analysis of data has become more accessible to analysts resulting in modelling
systems ranging from one-class classifying to multi-class classifying models (Oliveri and
Downey, 2012). Consequently, because ICP-MS and ICP-AES analysis protocols can produce
an extremely large amount of data, analysis and interpretation of these data now commonly
employs the use chemometric methods.
One class modelling is an effective chemometric technique for the analysis of multi-variant
data where only one class is known. This approach is beneficial as it allows for the testing of
the compatibility of unknown samples to the class being modelled and does not require the
sampling of representatives from any other populations (Oliveri and Downey, 2012;
Gnanadesikan, 1997; Hand, 1997). When the question being investigated is “Does this
material relate to similar material, contained in a data base?” this type of modelling can be a
powerful tool. However, as material that has not been sampled has the potential to overlap
with the sampled class as ambiguous assignment of a sample is possible in one class
modelling (Oliveri and Downey, 2012). Furthermore one class modelling can only include or
exclude an unknown from a single class and it is thus not useful for geographic assignment
when multiple categories of interest are known.
85
The provenancing of paper and paper products and various inks to a geographic region of
origin or to a batch of material produced at a factory or manufacturing location typically
requires more than one class or location to be defined. For this reason most studies have
sought the use of a discriminant or multi-class modelling system (Boggia et al., 2002; Ariyama
et al., 2004; Forina et al., 2007; Gonzálvez et al., 2009; Lo Feudo et al., 2010; Watling et al.,
2010; Furia et al., 2011). Multiclass classifying models, as described by Oliveri and Downey
(2012), work by finding a delimiter, between two or more classes, which can be used to
discriminate between them. This creates classes that are distinct and do not overlap. The
type of delimiter used is dependent on the method selected. However, in all instances a
decision rule is assigned based on the delimiter whereby an unknown is assigned to one of
the classes studied depending on their compliance to the rule. As this discriminating delimiter
considers all classes involved, the classes investigated must be correctly defined and
thoroughly representative of all possibilities as they will critically impact on the decision rule
during modelling (Oliveri and Downey, 2012). Such multi-class systems are most beneficial
when a group of well-defined classes is known and assignment to a population is desired.
Depending on the type of problem, multi-class models can either be unsupervised or
supervised. As described by Hand (1997) and Gnanadesikan (1997), the unsupervised models
such as cluster analysis can be used to assess if there are any significantly different
groups/classes/or categories in the dataset, without a prior input from the user of the
perceived groups. Conversely supervised models facilitate identification of the known classes
by the user prior to analysis. The model rules are then constructed around the identified
groups to explain the differences between the groups (Hand, 1997 and Gnanadesikan, 1997).
It is the supervised models that are most beneficial to assignment testing as they allow the
unknown to be predicted into a class system as determined by the user (Hand, 1997) thus
allowing desired categories such as geographic region of origin, manufacturer and batches to
be assessed.
As a supervised classification model (Hand, 1997), Linear Discriminant Analysis (LDA) is
commonly used in provenancing studies (Padin et al., 2001; Ariyama et al., 2004; Lo Feudo,
2010; Watling et al., 2010; Furia, 2011) because it allows the known origins or associations to
be defined in the model. LDA models are developed in a step-wise, or iterative fashion to
determine differences between the groups by selecting single variables at a time. Variables
86
must be independent of one another to ensure the same discriminatory force is not selected
at each step (Gnanadesikan, 1997). The forward stepwise modelling method starts with a
very basic model and at each step a new discriminatory term is added that best describes the
differences between classes (Hand, 1997). This makes the model increasingly more complex.
The model produced develops linear combinations of the variables that best describe the
differences in the groups and determines a discriminate space (two or three dimensional) in
which the multivariate point can be graphically represented based on their eigenvectors
corresponding to the two largest Eigen values (Hand, 1997; Gnanadesikan, 1997). The LDA
separates out each sample on the basis of user defined groupings, and a visual
representation of how distinct the samples are based on the groups selected is produced on
the graph (Watling et al., 2010). When the user defined groups do not separate, they cannot
be considered significantly different based on their chemical composition. Where separation
does occur the user determined threshold determines if a classification is significant and thus
accepted and is an important user input to the model (Hand, 1997). For the most part, in this
thesis, LDA has been use as the discriminatory mathematical technique, although comparison
of the spectral profile (elemental fingerprint) has also been used as it can immediately give
an indication of differences and of comparability between the elemental signatures of
samples from the same production batch or country.

Selected paper samples (Table 3.6) were ashed to provide ashed material for analysis. Ashing
was achieved by setting fire to the paper sample and collecting the residue in a ceramic
evaporating basin. Data are recorded in Appendix 1 Table 3. Five individual ash samples were
prepared from half a sheet of five sheets of paper from each ream used in this study and the
corresponding other halves of the five individual sheets of un-ashed paper were used for

Fountain pen ink samples (Tables 3.9 & 3.10) used in this part of the experiment were
purchased from nationally and internationally based ink suppliers. An initial experiment was
undertaken on samples detailed in Table 3.9 to determine how much ink was required to
establish a reproducible trace element signature, as a reference signature, for all study inks.
Samples 211-222 (Black Schaefer ink) and 235-246 (Blue Schaeffer ink) were provided by a
TSW Analytical staff member (Rachel Scadding) and because they were bought some five
years prior to the current survey and have been used during the intervening period, have
been designated (Provided by Rachel) to distinguish them from other Black and Blue
Schaeffer ink samples in this study.

Following this the remaining ink samples (Table 3.10) were analysed to establish their trace
element signature and to identify if generic trace element signatures could be ascribed to
inks from different countries and whether the trace element signatures for individual inks
were unique enough to be able to identify batches of ink and inks back to recovered samples
as the basis of a provenance determination protocol. Sample numbers in these tables refer to
the analytical data detailed in Appendix 2 Tables 5-7. All statistical data from the analysis of
ballpoint pen and fountain pen inks is recorded in Appendix 3.

3.4 Sample Preparation – Solution
3.4.1 Paper
Small samples of paper, approximately 5cm x 5cm in size (approximately 200mg) were cut
from the original A4 sheets using plastic scissors and weighed to four significant figures
before being stored individually prior to dissolution and analysis to avoid contamination. The
paper samples were subsequently transferred to pre-cleaned, accurately weighed and
labelled Teflon beakers and 10mL of a mixture of individually quartz sub-boiling redistilled
93
nitric and perchloric acids (mixed by volume prior to use in 4 parts nitric acid and one part
perchloric acid) were added to each beaker. The Analar™ acids were purchased from Merck
Chemicals (Merck KGaA, Darmstadt, Germany). These acids can be easily mixed together as
there is no reaction between them during mixing; in addition the mixed acids can be stored
indefinitely as there is no deterioration over time. The Teflon beakers were then covered
using a Teflon watch glass, and the mixture left to reflux overnight on a hot plate at 180oC.
Following this, the Teflon watch glasses were removed and the mixture was left to evaporate
to dryness at approximately 200oC, after which time 0.5ml nitric acid was added, together
with 5mL of 18MegΩ resistance deionised water to dissolve the sample residue. Samples
were then left at 105oC for approximately two minutes for the residue to dissolve. Following
this the solutions were transferred to pre-weighed 50mL pre-cleaned propylene tubes, and
made up to 20g using 18MegΩ resistance deionised water. The samples were subsequently
analysed using solution based ICP-MS and ICP-AES protocols. Data are detailed in Appendix 1
Tables 1A -1E.
3.4.2 Ashed paper
3.4.2.1 Preliminary Study
A preliminary study was undertaken using two different paper samples (Paper One Premium
all purpose, made in Indonesia and Reflex Recycled Pure White, made in Australia). Eight
reams of paper manufactured in four different countries and sold by six different companies
were used in this experiment to investigate the reproducibility of the elemental signature of
paper following ashing. The samples used in this study are detailed in Section 3.3.2, Table 3.6
and results are detailed in Appendix 1 Table 3.
Paper samples (A4) were labelled and divided into two halves by tearing along a folded line
across the long axis of the paper. One half of the paper sample was placed in a porcelain
evaporating dish and set on fire using a cigarette lighter, the subsequently produced ash was
transferred from the evaporating dish to a pre-weighed glass vial. Subsequently,
approximately 0.05g of ash was accurately weighed (four decimal places) and placed into a
Teflon beaker which had been pre-weighed and labelled. The ash samples were digested in
94
precisely the same manner as the paper samples detailed in Section 3.4.1. The data obtained
from analysis of paper directly required 200mg of sample, while the analysis of ash only used
50mg. This was because when paper is ashed it loses weight and 50mg of ash is
approximately equivalent to 200mg of paper and consequently the use of 50mg of ash and
200mg of paper ensures that as closely as possible equivalently derived data are being
compared and that the same sampling statistics and the same area of paper is being used for
both experiments.
3.4.3 Ink
3.4.3.1 Reproducibility of elemental signature of ballpoint pen ink
For this experiment, twelve packets of ballpoint pens, (each containing between 5 and 50
pens) were selected randomly from the in-house collection. The samples used in this study
are detailed in Table 3.3 and data are recorded in Appendix 2 Tables 1 and 2. Three red, five
blue and four black batches were chosen to represent the colours for this study. With the
exception of Blue Pilot made in China, Blue Pilot 2 made in China, Black Pilot made in China
and Black BIC made in Mexico, (where four pens were used from each packet), five pens
were taken from each of the remaining packets. Each pen was disassembled and the ink tube
removed and weighed to four significant figures. Once weighed the tubes were squeezed to
remove a drop of ink into a pre-weighed, pre-cleaned Teflon beaker, again to four significant
figures.
Both the beaker and the ink tube were then re-reweighed to four significant figures. The loss
in weight of the ink tube and the increase in weight of the Teflon beaker were compared and
were required to match to three significant figures or the procedure was repeated. Nitric
acid:perchloric acid (4:1) mixed acid (redistilled, 10mL) was added to each beaker, following
which each Teflon beaker was covered with a Teflon watch glass, and the mixture was left to
reflux overnight on a hot plate on 180oC.
On the next day 5mL of redistilled nitric acid were added and the solution was left to reflux
for another 3 to 4 hours at 180oC before the Teflon watch glass was removed from each
beaker and the mixture evaporated to near dryness at 200oC. After this, 0.5mL redistilled
nitric acid was added followed by approximately 2mL of 18MegΩ resistance deionised water
95
and the mixture left to warm for approximately 2 minutes at 105oC to dissolve the resulting
sample residue. The solution was then transferred to a pre-weighed, pre-cleaned 20mL
polypropylene tube and made up to 10mL using 18MegΩ resistance deionised water. The
volume of water added to make the final solution was, of course, not accurate and
consequently the final tube plus solution was reweighed to three significant figures and the
final volume calculated as a mass in grams. The samples were subsequently analysed using
solution based ICP-MS and ICP-AES protocols.
.
3.4.3.2 Comparison of the elemental distribution patterns for the same colour and
manufacturer of selected ballpoint pen inks
Five ink tubes were selected from each of ten different batches of BIC BLUE CRYSTAL
(Manufactured in France), five tubes from each of ten batches of BIC BLACK CRYSTAL
(Manufactured in Mexico), and five tubes from each of six batches of BIC RED CRYSTAL. A
description of the samples used (57-186) is given in Section 3.3.2 and the data produced in
this study is detailed in Appendix 2 Table 2. These samples were subsequently analysed using
solution based ICP-MS and ICP-AES protocols.
3.4.3.3 Effect of sample size on the reproducibility of the trace element signature of fountain
pen inks
Four different sample masses (approximately 0.02mL, 0.05mL, 0.1mL, and 0.2mL) from seven
different fountain pen inks were used in this study. The varying masses were used to
establish the suitable volume needed to obtain reproducible data for the analysis of fountain
pen inks using solution based protocols. While it was realised that this volume of ink may not
be available for conventional forensic studies, it was felt that an indication of the precision
variations of the elemental signature within the bottle of ink would be obtained by
undertaking this experiment and the data would be robust enough to establish the elemental
signature of the ink that could be used in a data base to try and establish if generic
indications of ink trace metal assemblages could be used to establish country of origin or
batch of origin. In this way if either of (or both) batch and country of origin could be
determined using trace elemental signatures then the trace elements that determined this
could be found and used to determine these factors when smaller volumes of ink were
available in actual forensic cases. In addition, the accurate determination of trace metal
96
concentrations would serve to conform the validity of the hypothesis that inks could be
provenanced on the basis of their trace elemental signatures whether this could be used in
forensic investigations or not.
Samples consisted of (Parker Black, Parker Blue, Schaeffer Black, Schaeffer Blue, and
Schaeffer Red). A description of the samples is given in Appendix 2; Table 3. Samples were
transferred to previously weighed Teflon beakers using a micro-pipette. The transfer of ink
from pipettes cannot be accurately controlled as “hang up” of ink on the plastic of the
pipette tip always occurs. Consequently, while the pipette transfer mechanism gave a
“qualitative” idea of volume, the masses of each transferred sample were recorded to four
significant figures to ensure the best chance of obtaining analytical precision and the ability
to cross compare data. 10mL of a nitric acid:perchloric acid mix (redistilled, 4 nitric acid:1
perchloric acid v/v) were added and the beakers covered with a Teflon watch glass prior to
overnight refluxing at 180oC. The rest of the dissolution procedure was the same as already
detailed in Section 3.5.3.1. Samples were analysed in triplicate using ICP-AES and ICP-MS
protocols.
3.4.3.4 Reproducibility of elemental signature of fountain pen inks.
For this experiment, an additional thirty five bottles of fountain pen ink (blue (15), black (16)
and red (4)) were investigated. Data are detailed in Appendix 2 Table 4. The data for the
seven previously analysed inks (2mL volume) were also added to this data set for provenance
determination studies. Each ink was analysed in triplicate to establish the degree of
reproducibility of each chemical profile in each sample and to obtain an indication of the
reproducibility of the analytical method. Approximately 2mL volumes of each sample were
transferred to dissolution vessels using micro-pipettes and each transferred mass accurately
recorded to four decimal places. As previously stated, while very little relative differences
between mass and volume transfers to dissolution vessels was determined because of
“relative hang up” of the relatively large volume of ink used (2mL), it was nonetheless felt
that it was important to achieve the best possible accuracy and so consequently samples
were measured using mass rather than volume. The volume/mass measurement was decided
upon after experimenting with different volume/mass measurements in Section 3.5.3.3 and
while all masses used in this experiment essentially produced the same quantitative data it
was decided that the larger volume (2mL) produced analytical solutions that were higher in
97
concentration for all analytes and would therefore gave better analytical precision.
Consequently, the 2mL volume was used for all experiments in this Section. The ink samples
were digested in the same manner as the ink samples detailed in Section 3.5.3.1.
3.5 Sample Preparation for LA-ICP-MS
3.5.1 Paper
Paper samples from three different reams of paper were used in this experiment and were
selected randomly from the different manufacturers studied in this thesis. Each paper sample
was analysed six times to provide blank values for the analyte composition.
In addition, these samples were marked using nine different inks from different
manufacturers. The ink colours consisted of three blue, three black, and three red with each
ink being applied to each paper sample. Paper sample one is Double A premium (Thailand),
paper sample two is Reflex Recycled Pure White (Australia), and paper sample three is Paper
One Premium Presentation (Indonesia). In total fifty-four samples of ink on paper were used
for each paper type in this study making a total of 162 samples. Following marking, the
samples were cut to provide a Section small enough to be mounted on a Perspex disk
(approximately 1cm2 using a double-sided tape and subsequently analysed using Laser
Ablation ICP-MS. Results are detailed in Appendix 5 Table 1.
3.5.2 Pencil
Paper Mate pencil lead samples 1, and 2 (made in China of hardness 2B), and Columbia pencil
lead samples 5, and 6 (made in Indonesia of hardness 2B), were used in this experiment. The
pencil “lead” samples were extracted from their wooden housing, labelled and mounted on
Perspex discs using double sided tape prior to be analysed using LA-ICP-MS.

3.7 Calibration and Quantitation
Quantitative calibration is based on measuring the intensities of all analytes in a number of
calibration standards that represent a range of concentrations. Calibration solutions are
prepared in 5% v/v dilute redistilled nitric acid, by serial dilution of Merck Certified Standards.
The concentration range of these standards is, wherever possible, calculated to cover the
range of concentrations present in the samples. Using these standards, a calibration curve is
developed with counts per second data being converted to concentration using this
100
calibration curve. On the basis of this relationship, pre-programmed software in the
instrument is designed to calculate the concentration of all analytes in the samples. However,
even though this method is appropriate for calculations of concentration where there is no
interference, or where the interference is well known and can be mathematically corrected
for by the software, all analytical data in this thesis have been manually calculated, using
counts per second data after interference correction has been performed and checked by the
analyst.
3.7.1 ICP-AES Calibration
Multi-element standards (1, 2, 5, 10, 20, 50 and 100µgmL-1) were prepared using serial
dilutions of a series of 1000µgmL-1 Merck™ standards. The dilutions were made using
redistilled nitric acid which had been made up to a 2% v/v mixture using 18MegΩ resistance
deionised water.
3.7.2 ICP-MS Calibration
Multi-element standards (1, 2, 5, 10 and 20µgL-1) were prepared using serial dilutions of a
series of 10µgmL-1 Merck™ multi-element stock standards. The dilutions were made using
redistilled nitric acid which had been made up to a 2% v/v mixture using 18MegΩ resistance
deionised water. Internal standards (2µgL-1 Rh & Ir) were contained in the dilution acid.
3.7.3 Isobaric Interference Correction in ICP-MS analysis
Isobaric overlap and polyatomic interferences are the most common error associated with
reported ICP-MS data (Lam, McLaren et al., 1995). Interferences are particularly detrimental
in ultra-trace element analysis as the concentration of many analytes is extremely low and
often approaching the detection limit of the technique. Under these circumstances, it is often
difficult to distinguish the analyte signal from the background, a situation made significantly
worse if isobaric interference is contributing to the signal as is often the case for arsenic,
vanadium and chromium (Pick, Leiterer et al., 2010). These interferences occur when
reactions in the sample matrix, air, argon in the plasma or water result in the formation of
polyatomic species that overlap the mass of analytes of interest (Koppenaal, Eiden et al.,
2004; Pick, Leiterer et al., 2010). A wide range of correction protocols have been developed
101
to deal with this problem from changing the dissolution method or instrumentation set up, to
mathematically accounting for the error post analysis (Lam, McLaren et al., 1995).
Mathematical correction post analysis is one commonly employed procedure to account for
polyatomic interferences (Krushevska, Waheed et al., 1998; Catarino, Curvelo-Garcia et al.,
2006 and Bednar, 2009). Mathematical corrections all rely on the use of known natural
isotope abundances to develop a correction factor that can be used to account for
interferences at a given mass (Brown et al., 2004). However, the manner in which this is
conducted can vary depending on the mathematical model and the matrix of interest. For
arsenic (75m/z) for example, correction for chloride interference (40Ar35Cl) can be conducted
by directly measuring the signal at both 75 and 77m/z and 82 and 83m/z (Lam, McLaren et al.,
1995; Brown, Yardley et al., 2004; Catarino, Curvelo-Garcia et al., 2006; Pick, Leiterer et al.,
2010). The signal at 82m/z can be caused by 82Se and 82Kr and at 83m/z by 83Kr. Consequently,
removing the contribution of krypton on the 82m/z signal will leave only selenium
contributing to that signal. The relative ratio of 82Se to 77Se will allow the residual counts on 77m/z to be attributed to 40Ar37Cl which in turn can be used to remove the 40Ar35Cl
contribution to the 75As signal and allow calculation of the actual amount of arsenic in the
sample. The problem with all these calculations is that each one has a precision associated
with it and the combination of all the variables at each stage of the correction procedure will
ultimately compromise both the detection limit of arsenic and also the analytical precision
associated with its determination (Zhou and Liu, 1997).
3.7.4 Detection Limit.
Coefficient of variation values for each analyte were used to determine the detection limits
for the study elements (Watling, 1977). The coefficient of variation of the analytical data was
calculated for each analyte by using data from the analysis of ten replicates of the blank and
comparing the variation in CPS data to the relative calibration curves for both techniques.
The detection limit was then calculated as both two and three sigma. Data are presented for
ICP-MS and ICP-AES analysis in Table 3.16 and 3.17 respectively.

3.8 Sample Analysis – Laser
3.8.1 Optimization
The ICP-MS instrument was optimised at the beginning of each analytical run in order to
achieve optimum operating conditions (highest CPS values for 59Co, 115In, 140Ce, 172Yb and 232Th. Tuning was performed by continually ablating a NIST 612 glass standard. During this
period the ion beam was focused by adjusting the ion lenses. After this the analogue and
pulse detectors were adjusted to ensure a linear relationship between instrument response
and isotopic concentration. Selected isotopic ratios (140Ce16O, 232Th16O, 140Ce2+) were
investigated in real time to observe and potentially counteract interferences from oxides and
from double-ionization of elements. The gas flow rate and gas composition were also
adjusted to reduce oxide interferences. Response ratios between high and low mass isotopes
were investigated and the voltages to the quadrupole and the ion lenses were adjusted to
observe and reduce, as much as possible, any mass bias. A set of generic sample analysis
conditions for the LA-ICP-MS are detailed in Table 3.18 and a list of tuning parameters given
in Table 3.19.

3.8.2 Analytical Method
3.8.2.1 Spot Ablation Method
After instrument tuning, the samples were placed into the laser cell and held in place using
either Blu-Tac™ or cyanoacrylate glue. The distance between the top of the sample and the
base of the laser cell were adjusted to a consistent distance for all of the samples and all
samples were levelled to ensure they were at right angles to the direction of the laser beam.
Once introduced into the laser ablation cell, the cell was purged using an Ar/He carrier gas for
a period of 90 seconds to remove any air that may be present. The area of ablation on the
sample was manually selected using the laser ablation software and data collection was
initiated for 5 seconds with the laser switched off to obtain a background signal. This
procedure also allows a baseline to be determined as a reference point for the subsequent
analytical run. After the five seconds had elapsed, the laser was switched on and sample
ablation commenced. After the 30 seconds of ablation the next sample location was selected
and the procedure was repeated until all analytical sites on the sample had been ablated.
A set of standards was run regularly throughout a typical LA-ICP-MS analytical period of
approximately eight hours. The NIST 610 standard was used to establish the optimum
ablation conditions at the beginning of a sample run and then reanalysed every 45 minutes to
facilitate drift correction throughout the day. A set of cross-over samples (samples that had
been analysed in a previous run and were re-analysed in the current run) were analysed at
the beginning, middle, and end of the analysis period. These samples were analysed in every
analytical period throughout this study and their frequent analysis facilitates achieving
reproducibility of data between runs.
3.8.2.2 Traverse Method
Initial setup for this procedure was identical to that described in Section 3.2.2.1. Following
the initial setup, the analytical sequence incorporated a 10 second Ar/He purge prior to an
ablation period of 90 seconds. After the ablation of a single traverse line, the process was
repeated for any additional lines required for the sample analysis. Samples were analysed
one at a time with repeated lines being run on the sample before a new sample was
introduced into the laser cell. After a sample was removed from the laser cell and a new
105
sample was placed into the cell, the cell was purged for 90 seconds and the procedure was
repeated.
3.8.2.3 Isotopes Determined
The majority of LA-ICP-MS analyses were performed with laser ablation taking place at a
single site on the pencils and as a traverse on the paper and ink on paper samples. An
extensive range of analytes and corresponding isotopes were chosen for determination
(Table 3.20) but following analysis of trial samples it was apparent that certain analytes were
only ever present in ultra-trace concentrations and/or were consistently below the detection
limit for LA-ICP-MS analysis. These analytes were removed from the initial analytical
elemental suite (Table 3.21) as their lack of consistent presence above the detection limit
renders them inappropriate for use in data interpretation protocols. Nonetheless, an
extensive suite of analytes was able to be determined for each sample.

Chapter 4 Results and Discussion 4.1 Paper
4.1.1 Reproducibility of the elemental composition within a single sheet of paper.
Fifty one different reams of paper were collected during the initial eighteen months of this
investigation. This material served the basis of the preliminary investigation into both
whether it was possible to obtain reproducible trace element profiles from paper and
whether the differences between both countries and batches of paper from those countries
would be different enough to facilitate the establishment of a trace element based paper
data base or not. A single sheet of paper was selected randomly from each of these fifty one
individual reams of paper in order to investigate, initially, if the trace element distribution
within a single sheet of paper was uniform. These samples were selected to represented
paper manufactured by different manufacturers in different countries and therefore,
because the cost of the paper and the countries of origin are wide ranging, this study also
was able to determine if the uniformity of the chemical signatures in paper were dependent
on either country of origin or cost, or indeed both.
Samples used in this initial study are detailed in Table 3.3; Section 3.3.1, and Appendix Table
1A. Samples were analysed for 61 elements. Paper was oriented in the portrait style and sub-
samples taken at the top middle and bottom of each sheet. Samples of paper from four
different manufacturers and countries were randomly chosen as examples to demonstrate
the reproducibility of the elemental signature within single sheets of paper (Figure 4.1). All
samples were independently dissolved and analysed. Data for all single sheet comparisons for
the 51 reams of paper used in this Section are detailed in Appendix Table 1A. Data for the
average elemental composition and reproducibility of the elemental signatures of the paper
samples used in these Figures are detailed in Table 4.1. From the data detailed in Figure.
4.1A-D, it is apparent that the trace elemental signature for the majority of elements within a
single sheet of paper is extremely reproducible. The actual data used in this Figure are
detailed in Table 4.1 where the average, standard deviation, and coefficient variation
percent, are also given. These values confirm the reproducibility of the analytical data and
highlight which elements exhibit the highest levels of reproducibility.
107
With reference to Figure 4.1 A-D, it can be seen the inter-element association pattern that is
obtained from each of the three triplicate analyses for each sheet of paper is essentially
identical. This means that in the event of a trace back investigation being undertaken, it is not
essential to take a reference sample from a particular part of a sheet of paper as the
elemental profile across any sheet of paper is essentially identical. This means that even
when it is not possible to identify exactly where a piece of paper comes from in a sheet it will
be representative of that sheet. However, it is recognised that there are some analytes that
show slight variations in concentrations within the sheets, mainly due to the fact that their
concentrations are at or near the detection limits for the technique. Nonetheless, providing
the differences in the trace element signatures within a sheet are less than the differences in
the trace element signatures between sheets from different brands of paper, then trace back
of a piece of paper to brand of origin can still be achieved unambiguously.
The data, with respect to the inter-element association patterns for the four different paper
types used as an example of results for this experiment, are detailed in Figure 4.2. As can be
seen from reference to this Figure, there are very large differences between the trace
element assemblages for these four different papers. This is true even for trace and ultra-
trace levels of analytes, such as the results for the rare earth elements where, while the
pattern of these elements is the same for all paper samples, their relative concentrations are
different. In these cases, with respect to the major element concentrations (sodium to iron in
Figures 4.1A-D and 4.2), the variations reflect mainly the concentrations and types of fillers
used in the paper’s production. This is especially interesting for sample 12 where the high
aluminium and low calcium are reflected by a high rare earth element profile. This is
surprising and reflects the use of a high rare earth content clay as a filler, a situation possibly
reflecting the use of a marine clay, and in this case a high magnesium marine clay. Under
these circumstances it may be possible to identify the origin of the filler as well and further
confirm the origin of the paper concerned. The principle of this observation is likely to be
demonstrated in all types of paper and highlights the fact that the use of elemental profiles in
paper may be able to provide far more information than simple concentrations alone as
fillers usually are of geologically based rather than artificial in origin and therefore reflect a
basic pre-cursor rock geochemistry that may much more easily reflect country of
manufacture than simple reference to analyte concentrations alone. Reference to Table 1A in
108
the Appendix further confirms the excellent comparability within a single sheet of paper for
all fifty one samples investigated. Furthermore, while the experiment detailed in this Section
was designed to investigate the reproducibility of the elemental signature within a single
piece of paper the data can also be used to give an initial indication of the relative variation
of elemental signatures between the four different papers used to show this association
(Figure 4.1). Because the reproducibility of the elemental signatures of these papers is
excellent an average value for each paper can be taken and plotted against equivalent values
for the other three (Figure 4.2). From this Figure, it can be seen that there are obvious
differences between all four paper samples. The fact that the differences between paper
samples are considerably greater than the differences in the elemental signatures within a
single sheet is the hypothesis studied in this thesis, and from Figure 4.2 it is apparent that
these differences can easily be seen. Consequently, differences between the trace element
signatures of paper manufactured in different parts of the world have the potential of being
easily recognised and recorded in a data base for retrospective examination. Furthermore, it
may be possible to establish variations in the trace element signature of the paper produced
by the same manufacturer over time. On the basis of this experiment it can be concluded
that any sample taken from a single sheet of paper will have an elemental signature
representative of that sheet.

4.1.2 Reproducibility of the elemental signature within a single ream
While it has been successfully demonstrated that reproducibility of elemental signature
within a single sheet of paper is excellent, it is necessary to establish how reproducible that
signature is within, and between reams, and batches of paper for the technique to be
forensically useful in the real world. Nine reams of paper from five different countries,
collected between six and ten months after the initial collection of paper detailed in
Appendix Table 1A and referred to in Appendix Table 1B, were used in the initial component
of this investigation. This type of collection framework was undertaken in order not only to
determine the reproducibility of the elemental signature within a ream of paper but also to
be able, where possible, to cross reference this signature with that from paper samples
collected earlier and detailed in Appendix Table 1A.
Five sheets of paper were selected from each of the nine reference reams. Samples were
selected from the top (sheet 1) and at sheet 101, 201, 301 and 401 from each of the reams.
An approximately 5cm by 5cm square was cut from the centre of each page (approximately
200mg), weighed to four decimal places and dissolved as detailed in Section 3.4.1. The
samples used in the initial study are detailed in Table 4.2.

It was found that the trace elemental signatures for the majority of elements within a single
ream of paper were extremely reproducible (Table 4.3). The excellent reproducibility of the
majority of analytes can be seen with reference to Figures (4.3 A-I) and in Appendix Table 1B.
In general, and as expected, the results indicate that there is a generic elemental signature
for paper (Figure 4.4). However, the relative concentrations of the analytes do vary especially
when it comes to the fillers such as titanium, strontium and barium. It is extremely difficult
to grasp the true significance of these differences between papers and also to understand
just how equivalent the data are for the individual reams of paper by reference to tables and
the graphs depicted. Consequently, Linear Discriminant Analysis (LDA) has been used to plot
the data to show these aspects (Figure 4.5).
In Figure 4.5 A the entire data set of analytes (61) has been used and while it is possible to
verify the similarities within individual reams of paper the variation in the F2 dimension is
trivial. Consequently, the data were replotted with those analytes that exhibited low inter-
batch differences removed. When this was undertaken (Figure 4.5 B) it was possible to see
not only the close association of the elemental concentration data for all reams of paper, but
116
also the fact that there appeared to be a generic association for paper produced in the only
two countries that had more than one different ream of paper investigated in this
preliminary study, Australia and Indonesia. This aspect will be investigated further later in the
thesis.
However, at this stage of the investigation it was interesting to determine which, if any, of
the analytes determined were generically associated with each manufacturing country as this
knowledge may provide a basis on which to pre-screen data to suggest country of origin
before detailed investigations are undertaken. In addition, because paper is a natural
product, the trees used in its manufacture will remove trace and minor elements from the
soil and concentrate them in their wood. These elements will vary depending on the pre-
cursor geology to soil production and will reflect the areas in which the trees are growing. In
many instances it is not possible to remove these elements during paper production and they
will survive the processes involved to be retained in the paper produced. Understanding the
source and reason for any differences in the trace element assemblage within the paper will
facilitate the identification of any anomalous elemental levels in the paper and these
observations have the potential to be used in any eventual data base to suggest a possible
country of origin of at least the trees used for the manufacture of the specific paper on
question. Consequently, the data in (Appendix Table 1B) were carefully scrutinised and it was
possible to construct a table of anomalously high analyte concentrations in individual reams
(Table 4.4). In so doing the possibility of a generic elemental signature for papers from
different countries, independent of manufacturer, is strongly apparent. In addition, specific
aspects of the manufacturing process also become apparent. If examples of these relative
differences between papers and countries of origin are also plotted (Figure 4.6 A-G), the
magnitude of differences can be easily seen and the inter-county of origin elemental profiles
much more clearly demonstrated.

While there are significant levels of titanium in most of the papers (Figure 4.6A), the highest
titanium levels are found in the Australian Reflex Recycled Pure White paper (sample number
54). This material is obviously the primary filler and whitening agent used in this paper and
the high titanium is also reflected in the high scandium, manganese, zirconium, iron,
tungsten and thorium as all these elements are present in the mineral sands from which
titanium dioxide pigment is extracted and for which the Australian mineral sands industry is
famous worldwide. The Office Works Ultra-White Premium and the second ream of Reflex
Recycled Pure White (sample number 60) also have relatively high levels of titanium and both
are made in Australia.
With respect to growing environment, the data in Table 4.4 indicate that the high
phosphorus in Brazilian paper, used in this investigation, is probably derived from old forest,
or at least deciduous forest, as trees that are grown in old soil, which has had centuries to
mature and contains high leaf litter, contain significantly more phosphorus than new and
sandy soils and the growing cycle of deciduous trees is much longer than that of the pine
forests used in most other countries for paper production. These fast-growing conifers
sequestrate less phosphorus than their much more slowly growing deciduous cousins and
consequently paper made from them contains far less phosphorus.
Lithium (Figure 4.6B) is highest in all three Indonesian papers (sample numbers 53, 57 and
59), and as indicated in Table 4.4, molybdenum is also highest in the same Indonesian papers
(Figure 4.6F). There is an indication that samples 54 and 60, both derived from Australia and
named Reflex Recycled Pure White, have elevated levels of molybdenum; however the Office
Works Ultra-White Premium paper does not. This could indicate differences in the feed stock
processed by different mills in Australia and may be indicative of the possibility of identifying
mill, and hence source, of origin of the individual papers even though they could be produced
for the same wholesaler.
One further interesting aspect is that the Argentinean paper is high in silver. As its name
suggests Argentina is a country whose history is steeped in the production of silver and is
recognised as a “Silver Province” by exploration geologists. This being the case it would
appear that the trees being used to produce the paper used in this study are grown on a
131
silver rich soil and it may be possible to use trees as indicators of sub cropping silver
mineralization.
On the basis of this preliminary experiment it is a reasonable assumption that any sample
taken from a single ream of paper will have an elemental signature representative of that
ream. Therefore, it should be possible to trace a single sheet of paper back to the
manufacturing batch and also to the country of origin.
4.1.3 Variations in the elemental composition of paper with respect to country/manufacturer of origin.
An additional seventy-five reams of paper were purchased from national and international
suppliers to try and investigate the possibility, indicated in Section 4.1.2, that there were
generic differences in paper that were based on country/manufacturer of origin. The papers
involved in this investigation are detailed in Appendix Table 1D. In collecting these papers at
least three reams were obtained of each type of paper and in one case and extra twelve
reams of X Fuji Xerox Paper were collected from various departments around the University
over a four-month period to try and obtain different batch numbers. In this collection of
paper from around the university it was possible to have access to fifteen different reams of
paper and to compare profiles of these papers covering nearly a two-year interval.
In the study detailed in Section 4.1.3, a single sheet of paper was used to characterise the
trace element composition of each ream as previous investigations, detailed in this thesis,
had indicated that it was only necessary to use one sheet of paper to obtain the chemical
characteristics of the whole ream and it was necessary to keep analytical costs as low as
possible. When the data are plotted with respect to an individual analyte an equivalent series
of figures can be constructed (Figure 4.7 A-I). In these figures it is possible to see the generic
patterns of the different countries yet again, although the fact that very different types of
paper from within a single country are being plotted in these Figures makes generic
specificity difficult. A key to the abscissa axis is given in Table 4.5. As can be seen by reference
to this table, the majority of samples studied in this Section come from Australia and will be
the subject of a more detailed investigation in Section 4.1.4. As can be seen in Figures 4.7 A-I,
there are significant differences between samples of paper from the different countries used.
132
However, there are also differences between the different paper reams coming from
Australia. The Indian Clarion sample (Figure 4.7 A) seems to have by far the highest
magnesium concentration of any of the paper samples and this high magnesium is
characteristic of all three reams used in the study. The magnesium possibly represents
magnesium carbonate which is a relatively insoluble carbonate, even in acid, and is also used
as a whitening agent. None of the other six countries studied seem to have anywhere near
this amount of magnesium in their paper.

The Brazilian paper (Figure 4.7 B) seems to have the highest phosphorus content of all the
papers as it did in the previous study (Section 4.1.2) but other countries seem to have varying
concentrations of this element which may reflect a combination of deciduous and coniferous
trees in their paper. Two countries, France and Indonesia (Figure 4.7 C) seem to have the
highest copper in the paper studied and this may reflect again the source of the trees as it
seems unlikely that French manufacturing processes would add copper to their paper. This
tentative observation may be a clue to determining if paper is manufactured in one country
and cut, packaged and sold in another as the secondary country’s product. It is interesting to
note that manganese seems to be high in all Australian papers (Figure 4.7 D), while in the
other six countries studied in this Section it is very much lower. In addition, manganese
seems to fluctuate within Australian papers making it a possible paper type or mill of origin
discriminating element. Arsenic (Figure 4.7 E), has obviously been introduced during the
growing of paper and shows very distinct differences both within the Australian population of
papers and between individual countries, and could be an extremely good indicator element
for brands of paper. Strontium is again extremely high in Brazilian papers (Figure 4.7 F),
133
possibly indicating its use as a whitening agent and filler. Distinct differences exist between
Australian papers and those from the other six countries studied (Figure 4.7 G-I), zirconium
(Figure 4.7 G) indicates, as suggested in Section 4.1.2, an association with areas of titanium
production from mineral sands. This element too could be indicative of state of origin of
Australian papers as not all states in Australia have extensive mineral sands deposits.
Surprisingly, Australian paper has, in general, the lowest concentrations of uranium present
in the seven countries paper studied. The highest levels of uranium in paper come from India,
while Brazil, Sweden and the UK all have relatively anomalous levels of uranium in the paper
from their countries studied in this section.
Again it is difficult to distinguish differences between the different paper samples simply by
looking at diagrammatic representations of elemental association patterns. Consequently, it
is always essential to undertake statistical interpretation using LDA plots. Examples of these
plots can be seen in Figure 4.8 A-C. From these plots it is apparent that there is an excellent
association of data for all individual data sets of paper (in some cases up to nine different
reams) and essentially each individual paper group can easily be isolated from each other.
The fact that each paper group is so distinct and that the elemental signatures are so precise
adds further to the hypothesis that it will be possible to take the protocol of paper
provenancing detailed here and use it even to the level of batches of origin. From the data
shown in Figures 4.8A-C, it is apparent that a number of groups of paper are able to be
isolated from each other, either using the complete data analyte set (4.8A), major (4.8B) or
trace (4.8C) elemental assemblages. Using LDA it is possible to initially separate paper groups
from Brazil (10), India (13), Indonesia (14) and the United Kingdom (16) using a combination
of total element signature (48A), major element (all analytes with concentrations above

1ppm) (Figure 4.8B) and trace element signature (all analytes with concentrations below
1ppm) (Figure 4.8C). It is especially interesting to note that in the LDA diagram representing
the major element concentrations (Figure 4.8 B) there are only two groups of data, one
representing all other papers studied in this section and one representing the Indian
material, suggesting that the Indian paper is made from completely different parent material
than the rest of the papers studied. This probably indicates that this type of paper may even
represent a different type of tree or plant used in its manufacture as the trace element
signature separates the papers out more than the major element signature.
Obviously with reference to Figure 4.8B, the major element composition of the Indian paper
is very different from the rest of the papers in this study. However, there is a significant
spread of data in the remaining two LDA plots (Figures 4.8A and C). In Figure 4.8A there are
three sets of data (three reams of paper in each set), representing samples from India,
Indonesia and the United Kingdom (UK), are outside the main cluster of data points. The
Indian sample set has already been addressed but the two other sets of data, from the UK
and Indonesia, obviously isolate from the other data sets by virtue of variations in their trace
elemental signatures. If the trace element based LDA is inspected (Figure 4.8C), it is obvious
that these clusters of paper again isolate from the main data set and that an additional set of
data representing Brazilian paper is also isolated. Each one of these four clusters is
represented by three reams of paper whose internal uniformity of trace elemental
composition is evidenced by the close association of data points. Consequently, because of
the extremely close grouping of the data within each individual data set, it is justifiable to
remove the sample data representing these reams of paper before progressing to undertake
a second series of iterative LDA plots.
In the second series of LDA plots detailed in Figure 4.9A-C are obtained. The majority of data
represented in these plots is obtained from the analysis of various different Australian paper
brands and even a cursory inspection of the LDA plots indicates that there are essentially four
or five clusters of data, one representing all Australian samples and the other three data
clusters representing paper from France and Sweden. The reason for indicating four or five
clusters (and not a definitive number) is obvious with reference to Figure 4.9B, where it can
139
be clearly seen that the Australian papers sub-group into two defined clusters based on their
major element (ppm) profiles.
The first major grouping of Australian papers contains paper from groups 1-6 (thirty samples)
inclusive while the second from groups 7-9 (twenty seven samples) inclusive. The two French
(six samples) and one Swedish (three samples) sets are completely isolated and it is
interesting to note that the two French sets of data associate with each other in all three
plots, pointing to a generic trace element signature in the two sets of paper and to the
possibility that this generic signature is country of origin dependent. The Swedish sample
remains isolated from the other data sets in all three LDA plots. While the Australian samples
do from two distinctive groups these groups are also co-associated again indicating a
potential generic, country of origin, trace element signature. Using the two sets of LDA plots
(Figures 4.8A-C and 4.9A-C) it has been possible to isolate all paper samples into country of
origin sets and to prove the consistency of the trace elemental signature of individual paper
reams within those sets. However, the biggest data set is for the Australian papers and
consists of fifty seven individual reams of paper. While obviously the extent of the paper data
base used in this study is limited, the protocols used do confirm the principle of the use of
inter-elemental association patterns for distinguishing between papers from different
countries.
If an iterative LDA approach is now used, and the data for those papers that can be easily
distinguished in the initial series of plots removed, (that is all the paper that does not come
from Australia) it is possible to sequentially remove sub-populations of paper that can be
individually identified and thereby isolate all the study paper groups (Figures 4.10 A-C). In this
series of plots it is quite obvious that, on the basis of the total elemental signature it is
possible to identify each ream of paper to a manufacturer, i.e. they are separated into
individual groups. This separation is largely based on their trace elemental profiles (Figure
4.10C); however, the major element signature confirms the separation of the various reams
into four clusters, possibly representing the four mills in Australia at which photocopying
paper is produced (Murphy, 2009). However, it is far too early to suggest that this
observation is any more than “coincidental” at this stage as it will be necessary to trace mill
140
of origin physically in the ground and then sample paper at site for this observation to be
confirmed and this is obviously the subject of follow up research.
While it may be considered as interesting to be able to determine the mill of origin, and
possibly establish a generic elemental signature for this mill, probably due to the different
nature of feedstock at each mill, this really is not important as long as the specific batch of
origin can be established and relevant samples traced back to that batch. The reason that mill
of origin may be of interest is that that mill may have a different supply chain from the others
and this may help to identify a possible distribution area and narrow down search protocols
in the event of a trace back.
4.1.4 Ash
It is not always the case that the “paper” present at a crime scene will be in a pristine
condition. It may be that a criminal could be trying to destroy a document or destroy
evidence of copying or practicing a forgery, for example forgery of a signature. Consequently,
it could be the case that the forger tries to destroy evidence by setting fire to it. In the case of
paper this is an obvious method of destruction of evidence as paper is extremely flammable.
In this case, it would be extremely useful of the trace element signature of the ashed paper
could be traced back to that of the original paper, especially if material could be read on it as
well and related back to a specific crime or attempted crime. Consequently, a number of
paper samples were randomly selected and an experiment undertaken where this paper was
burned and the ash trace elemental signature compared with that of the original paper.
Sample preparation and dissolution for this experiment has been described in Section 3.3.2.

4.1.4.1 Preliminary study of the elemental composition of Ashed Paper
Five sheets of paper from two reams of paper, Paper One-Premium All Purpose (Indonesia),
and Reflex-Recycled Pure white (Australia), Section 3.4.2.1 (Table 3.6) from different
manufacturers and countries were labelled, torn longitudinally in half, weighed to three
decimal Figures and each half set on fire and ashed. The ash was then collected and
reweighed and a loss of mass on ignition calculated.
A representative sample was then dissolved and analysed in the same way as the paper
samples Section 3.4.1. Data are detailed in Appendix 1; Table 2. The excellent reproducibility
of the majority of analytes can be seen with reference to Figure 4.11A-B. Having established
this excellent agreement in the elemental association pattern of the ash for these two
samples, an additional detailed study was undertaken using the remaining five samples of
paper in this experiment.
4.1.5 Reproducibility of the Elemental Composition of Ashed Paper
Five sheets of paper from each of seven reams of paper samples description Section 3.3.2
Table 3.6 from different manufacturers and countries were labelled, torn longitudinally in
half, weighed to three significant figures and each half set on fire and ashed Section 3.4.2.
The ash was then collected and reweighed and a loss of mass on ignition calculated.
A representative sample was then dissolved and analysed in the same way as the paper
samples Section 3.4.1 Data are detailed in Appendix 1; Table 3. Paper reams from three
different manufacturers of three different countries were chosen as an example to
demonstrate the reproducibility of the elemental signature of the ash. The samples are HP-
Every day paper sample number (56A-E/A) (made in Brazil), Office Works Ultra White
Premium sample number (58A-E/A) (made in Australia), and Paper One Premium
Presentation sample number (59A-E/A) (made in Indonesia). The excellent reproducibility of
all analytes in the ash can be seen with reference to Figures 4.12A, 4.12B, and 4.12C. One
further aspect of note, obvious in the comparison of these three plots is that the generic

signature of paper from all three countries is essentially the same. This is not altogether
surprising as the source and production protocol for paper is essentially the same the world
over. Furthermore, the generic trace element profile probably reflects the fundamental
biochemical processes taking place in the source tree species and it is distinctly possible that
changes in these profiles may reflect old and new growth forest and be useful in policing the
use of old growth material in modern paper production. The main sources of difference in
the trace element signatures between countries and manufacturer is therefore to be found in
fillers and occasionally in “rare” elements that have been taken up by the trees from site
specific locations. This aspect is why it is possible to use inter-element association patterns to
distinguish provenance of this type, and essentially all types, of material.
Elemental data for the ash of HP-Every day paper sample number (56A-E/A) (made in Brazil),
are shown in Figure 4.12A. The overlap of the “fingerprint” of the five samples detailed on
this figure for this paper ash is quite remarkable and indicates the reproducibility of the QC
and manufacturing process that are inherent in paper manufacture today. The same
remarkable “fingerprint” overlap is shown for Office Works Ultra White Premium made in
Australia, Figure 4.12B, and Paper One Premium Presentation made in Indonesia (Figure
4.12C). This aspect is extremely important as it improves the provenance determination
statistics and indicates that it should be possible to undertake even batch to batch
discrimination when there have been further improvements in the detection limit capabilities
of the techniques used. Because of the excellent reproducibility of the elemental signatures
of the paper ashes it is perfectly acceptable to represent each group of ashes with the
average ash data and to plot the three different papers together for comparison purposes
(Figure 4.13). From this figure it is apparent that, in spite of a generic similarity between the
elemental signatures of the ash from the three papers, there are definitely differences that
can be used to discriminate between each set of ashes.
The main differences between the paper ash samples are associated with fillers into the
paper, which are largely the result of manufacturing practices. However, trace element
differences such as those for copper, zinc, germanium, molybdenum and cadmium, improve
the chances of ash trace element chemistry being useful in the trace back of paper to generic
sources.
146
This observation, together with the definite possibility of comparing the ashed and un-ashed
samples and being able to relate these to each other further suggests that it will be possible
to identify ashed paper and relate it back to the original material and that there is significant
potential for this technique to be used in forensic investigations even after the “evidence”
has been “destroyed” by fire. This concept opens up a completely new area in forensic
investigations.
4.1.6 Ash to Paper Comparison
However, the most important point is not necessarily whether or not it is possible to
distinguish ashes from different paper samples from each other but more whether it is
possible to relate the ashes from different samples back to the original paper. In order to
achieve this comparison it is necessary to compare the ashed paper elemental signature with
that of the original un-ashed paper (Figure 4.14).
In this figure the inter-element association patterns for each set of ashes exhibit a uniform
relationship with the equivalent association patterns for the original un-ashed paper (Figure
4.14A-C). In addition, the relative differences between the association patterns for the ashes
and papers seem to be relatively consistent between all three sets of paper. The relatively
lower, in terms of counts per second, position of the paper inter-element association pattern
to that of the ash simply represents the loss of mass of the paper when ashed. With this in
mind it was decided to calculate the relative loss on mass of the seven paper samples used in
this study and determine a generic multiplication (normalization) factor to use to modify the
paper signatures and compare them to the ash values and in so doing remove the loss in
mass related gap between the two sets of data for each paper when comparing results
graphically. Data for the loss in mass of the seven paper samples is given in Table 4.6.

4.1.7 Applying the Ash Factor for Ash/Paper Comparison
From Table 4.6, it is apparent that the loss in mass on ashing is nearly the same for all
samples of paper, in fact if the loss in mass on ashing of all thirty-five samples is calculated it
is 75.89% +/- 2.8%, which amounts to an RSD of only +/-3%. Consequently, it was decided to
use an ash to paper mass ratio of 4.15 (100/ (100-76))/as a multiplication factor for the
concentrations of analytes in paper in order to plot them on the same graphs as the
concentrations in their equivalent ashes. Obviously, in the real world this factor would be
unknown. However, this approach is pragmatic and will allow easier visual comparison of
data for ashed material to a reference data base than simply comparing the data sets without
normalization. Comparison graphs, following normalization to ash concentrations, for all
seven papers are detailed in Figure 4.15 A-G and data are summarised in Figure 4.16. While it
is expected that some elements may differ relatively between the ashed values and the paper
values the comparison of elemental profiles or the two sets of data is nonetheless
remarkable. Even when the data for the ash and original material is combined the differences
between the sources of the paper is still absolutely discernible. However, relative comparison
of data is always subjective and, in court, could be argued one way or the other with the
distinct probability of confusing a non-scientific jury and resulting in a dismissal that may or
may not be valid. Consequently, it is necessary to subject the data to more rigorous statistical
interrogation before the use of this comparison method could be considered for court.
Consequently, all data (ashed and non-ashed) were plotted together to try and establish the
coincidence of the various populations (Figure 17 A- H). In Figure 17A and B, the entire data
set has been plotted (LDA Plot) using all analytes but with both validation and no validation
data used. The advantage of the validation data is that until the groups have been defined by

the software the validation samples have not been assigned to a group and therefore act as
an indication of the robustness of the methodology when it comes to interpretation of data.
In Figure 17A, all validation data fit into the correct data groups either in the ash or non-
ashed aspect of the data. In all cases the ashed data and the non-ashed data are co-
associated. However, a larger group, consisting of both Australian samples is difficult to
separate on the basis of the entire elemental suite. When the samples are re-run using no
validation samples there is complete separation of all relevant country of origin groups while
the two Australian sets of samples are again co-associated. While this may, to some extent,
be expected, it is nonetheless interesting to see that while the Indonesian groups separate
into sub-populations depending on brand, the two Australian groups, Office works Ultra
White Premium and Reflex recycled Pure White, group together possibly suggesting that
there could be a generic relationship between paper within countries of origin, if the original
raw product source is within that country. This aspect will be explored in more detail later in
this chapter.
When interpreting data of this sort it is essential to realise that there is to a large extent the
same influence on sub-group establishment placed on differences between analytes that
have relatively high concentrations and those with low concentrations. The problem here is
that the lower the concentration of a specific analyte, the nearer the data are to the
detection limit of the technique and by definition this means the greater is the
irreproducibility (lower precision) of the data. This irreproducibility is then used to identify
sub-populations and while it is true that the lower the concentration of the analyte the
greater are the chances that it is site specific and hence the more value it has in discriminant
analysis, data must be viewed with this in mind and cross referencing of conclusions
compared with data that have higher concentrations to establish of the final observations
with respect to provenance can be substantiated in any way. Consequently, in Figures 17C
and 17D (no validation samples) respectively, major and minor element LDA plots have been
run separately. From the major element data (Figure 17C), the Australian samples again
group together and two of the three Indonesian sample groups group together also. When
only minor and trace element concentrations are used in the LDA plot (Figure 17D), all groups
are separated. The ash samples and the non-ashed samples still co-associate confirming the
robustness of the technique. However, the fact that the major element concentrations cause
158
generic co-association of populations while the use of trace element concentrations causes
the separation of sub-groups which is extremely interesting. It implies that with larger and
more robust data bases it may be possible to determine generic elemental profiles for
individual countries of origin of the paper pulp using major (and possibly some minor)
element concentration patterns, whilst the use of trace and even ultra-trace elements
patterns may be used to identify origin in terms of manufacturer and possibly area of
production. This aspect may also make it possible to use this concept to determine if raw
pulp has been imported and additionally whether it comes from planted (new growth) or
indigenous (ancient) forest.
Again, when these data are plotted using LDA and including validation samples (separate
plots for the major (Figure 4.17E) and minor and trace elements (Figure 4.17F)), 100% of the
validation samples correctly fit into the groups that define the relevant sub-populations and
in this series of plots each individual sample suite can be unambiguously defined. Individual
scatter point data for each sample is also significantly reduced in these plots, which leads to a
much better resolution and identification of the sub-group and to the possibility that by
defining a reduced set of analytes, more relevant to each series of data under review, (Figure
4.17F and G), it may be possible to better isolate and separate individual sample sets based
on their manufacturer.
Although this approach was relatively successful, there was still some overlap of sub-
populations (Figure 4.17F), which could only be resolved when looking at the Australian and
Indonesian samples together and removing data for the Thai and Brazilian samples from the
data set before re-plotting (Figure 4.17G). Again, all validation samples were correctly
designated to their relevant sub-group, thereby cementing the original observation that it is
possible to determine provenance of ash material and relate it back to the original un-ashed
paper with a very high degree of certainty. From the data shown graphically in Figure 17, it is
obvious that by using a combination of the various LDA plots undertaken in Section 4.1.7, it is
also possible to determine country of origin and manufacturer of the paper and potentially,
with a larger data base, to also be able to determine the generic provenance of the pulp used
to make the paper as well.

4.2 Ballpoint pen ink
4.2.1 Reproducibility of elemental signature of ballpoint pen inks.
Having been able to determine the provenance of the paper so successfully, and if this
technology is going to be of use to forensic investigations, it is obviously necessary to try and
determine the provenance of both ink and pencil markings that have been applied to the
paper to a similar degree of precision. If this can be achieved it should also be possible to
determine the origin of ink and pencil markings on paper without having to remove them
from the paper surface or significantly damage evidence in order to obtain a sample for
analysis. In this series of experiments both ballpoint pen ink and fountain pen ink have been
investigated separately. Pencils have obviously also been investigated separately.
For the initial experiment with respect to ballpoint pen ink, twelve packets of ballpoint pens
(each containing between 5 and 50 pens) were selected randomly. Three red, five blue and
four black batches were chosen to represent the colours for this study (Section 3.3.3.1;
(Table 3.7)). Sample preparation and dissolution for this experiment has been described in
Section 3.4.3.1 and detailed data are given in Appendix 2; Table 1. With the exception of Blue
Pilot (China), Blue Pilot 2 (China), Black Pilot (China) and BIC Black, where four pens were
taken from each packet, five pens were selected randomly for analysis from each of these
packets. The reason for only selecting four pens for some groups was that these groups had
packets that only contained five pens (while all other contained between ten and fifty) and it
was decided to leave one complete and untouched pen in the packets of five for future
reference. All the inks from the 56 ballpoint pens used were analysed using ICP-MS, and ICP-
AES techniques that have already been described in detail. Three different brands of blue ball
point inks were used in this part of the experiment to investigate how reproducible the
elemental profiles of the inks are. Data are detailed in Appendix 2 Table 1. It was found that
the trace metal elemental concentrations for most of the elements within one brand of
ballpoint ink were extremely reproducible. The samples used for the initial study were Blue
BIC made in China samples 1-5, Blue Office Works made in China (Figure 4.18A), samples 10-
14 (Figure 4.18B), and Blue Paper Mate made in Malaysia samples 15-19 (Figure 4.18C). It is
almost impossible to determine the differences between the trace and major element
signatures for each individual ink for the five reference samples from each batch.

Reduced analyte elemental suite (B)
Figure 4.19 LDA plot of the data for the three ballpoint pen inks investigated in the initial survey.
However, there are significant differences between each of the inks (Figure 4.18D). The
generic signature for all of the inks is somewhat similar as all inks contain the same element
suite and the relative proportions between the elements are not expected to be very
different. However, there are sufficient differences between the total elemental signature for
the individual brands to be clearly separated when the data are plotted using LDA. (Figure
4.19). The choice of analytes, used for constructing the reduced analyte set LDA, is based on
the most important analytes facilitating the separation of sub-groups of samples given in the
original “Total analyte” based LDA. The analytes are ranked in order of usefulness for
separation purposes by the software used and this list facilitates selection of the most
relevant analytes that can be used for separation and grouping purposes. In choosing the
appropriate analytes to use as a reduced set it is essential that analytes at or near the
detection limit of the technique are excluded as their inclusion could inappropriately bias the

end result as differences may simply reflect analytical precision near the detection limit and
not represent real differences in analyte concentrations between samples. This screening
procedure has been adopted for all LDA procedures where a reduced data set of analytes has
been used.
4.2.2 Comparison of the elemental distribution patterns for the same colour and
manufacturer of selected ballpoint pen inks. (Appendix 2 Tables 2-4).
Five ink tubes were selected from ten different batches of ballpoint ink of BIC BLUE CRYSTAL
made in France, five tubes from ten batches of BIC BLACK CRYSTAL made in Mexico, and five
tubes from six batches of BIC RED CRYSTAL made in China, (Section 3.3.3.2; (Table 3.8);
Samples (57-186)). These samples were digested chemically and analysed using the ICP AES-
MS. Sample preparation and dissolution for this experiment have been described in Section
3.4.3.1 and results are detailed in Appendix 2; Table 2-4. Having established that the
elemental distribution patterns for the blue ballpoint pen inks were essentially reproducible
within manufacturing batch an additional nine batches of inks, two blue, three red and four
black, were incorporated into the trial data set to try and establish if there was the possibility
of a generic signature for the inks relating back to country or manufacturer of origin. The
data for the inks is described in Appendix 2 Table 2-4.
It was decided to use LDA plots to investigate these data as it was considered that the initial
experiments in this area had established that individual batches of ink would have essentially
the same or very similar inter-element association patterns and the scatter of data in an LDA
plot should therefore be minimal. When the data are plotted (Figure 4.20), it is obvious that,
while certain sets of samples are separated, there are some that are relatively closely
associated with each other. It is potentially significant that samples from blue Paper mate ink
made in China (4) and red BIC ink, also from China (7) are closely associated in the plot and
that both populations produce data sets that are extremely reproducible and do not overlap
(Figure 4.20 A). This observation may be significant in terms of generic elemental signatures
in the inks. In addition, the wide distribution of the data for group 9 (black Officeworks made
in china) samples is simply because the software has chosen to use three of the five replicate
168
samples to develop the association algorithm. Consequently, the data will not be well defined
and will spread within the cluster representing these samples. This lack of ability for the
software to define the population will, in the case of this plot, result in a less well defined
separation for other groups and this will affect the general population separation algorithm.
This is not a situation that is often repeated and additional plots of the data (Figure 4.20B),
define a much more realistic grouping for the data sets.

If the data for only the elemental distribution of black and red inks is plotted (Figure 4.21), it
is quite apparent that there is complete separation of all the relevant inks from each other
and that the grouping of data points is extremely good.
Figure 4.21 LDA plot for elemental data in black and red ballpoint pen inks
From these data, it is apparent that there appears to be no specific grouping associated with
colour, probably indicating that the colour is organic in nature, or to any remarkable extent is
the grouping associated with country of origin of the inks. The data also imply that there is no

generic signature associated with county of origin of ballpoint pen inks and that the only
association is within specific batches. This really is not a problem and confirms that each
individual batch of ink (to the extent that the study has so far investigated) has a unique
elemental signature which will lead to its definitive identification in any trace back situation.
4.2.3 Variations in elemental signature within batches for the three study ink colours
In this section five replicate samples of the inks from ten batches of BIC Crystal blue ballpoint
pens produced in France (samples were collected from different stores in France over a six
month period), five replicate samples of the inks from ten batches of BIC Crystal black
ballpoint pens produced in Mexico (samples were collected from different stores in Mexico
over a two month period) and five replicate samples of the inks from six batches of BIC
Crystal red ballpoint pen inks produced in China (samples were collected from different
stores in China over a two week period), were analysed. Data are presented in Appendix 2
Table 2. This set of experiments were designed to confirm that it would be possible to
determine the differences between batches of the same colour ink in a much larger set of
samples. Each different study ink colour was produced in a different country and the fact that
multiple outlets were used to collect each set of samples from, together with the period of
time taken to collect the samples, essentially increased the probability that the same batches
of ink were not present in any two replicate set of samples. A preselected study suite of
analytes was used for each of these studies and is indicated as a key to each of the LDA
diagrams detailed in the text. Although the use of LDA to identify sub-populations of each
batch of manufacture is extremely strong the initial investigation was to simply determine
the degree of co-association of the trace element assemblage in each ink colour to establish
whether there was a general trace element signature for each colour of ink in each country of
manufacture studied. This experiment was necessary because it is probable that the ink
colour is organic in nature and therefore trace element association patterns may represent a
country of origin only and not a batch of manufacture. If this was the case different colours of
ink coming from the same country would have a similar signature which quite obviously
would invalidate the technology. Consequently, a single LDA plot was undertaken to include
all sample data of all batches of the three colours of ink investigated (Figure 4.22).
171
Figure 4.22 LDA plot of the three different colours of ballpoint pen ink used in this study.
From the LDA detailed in (Figure 4.22), it is apparent that the three different ballpoint pen ink
colours can be easily differentiated from each other and that the groups representing ach
colour are extremely closely associated indicating that the manufacturing process is
sufficiently well established and employed that generically all blue BIC Crystal inks made in
France will have the same generic signature. Consequently, the close association of the
elemental association patterns for the different colour inks within individual batches of the
same ink colour makes it even more necessary to be able to distinguish batches of ink for this
technique to have value in forensic investigations. Following this initial investigation, the fifty
samples of BIC Crystal blue ballpoint pen ink manufactured in France were tested using LDA
(Figure 4.23).

Figure 4.23 LDA plot of fifty samples (ten batches of five individual pen ink samples) of BIC Crystal blue ballpoint pen ink manufactured in France (Group numbers refer to the individual samples of ink detailed in Appendix 2 Table 2).
From the data detailed in this figure it is apparent that one group (Group 1, Appendix 2 Table
2), are isolated from the rest of the data set. All other samples, while showing some degree
of separation from each other are, however, closely associated and consequently it is
necessary to undertake a series of LDA plots using reduced data sets to see if it is possible to
resolve the groups back to individual batches of ink. Consequently, a series of iterative LDA
lots was undertaken, firstly the samples representing Group 1 were removed and the data
replotted (Figure 4.24). In this figure it can be easily determined that Groups 2 and 4 from
well clustered and very separate groups from the rest of the data. Again, if the data from
these two groups are removed and the remaining data replotted (Figure 4.25A), it is apparent
that essentially three groups (Groups 3, 5 and 6) separate from the rest of the data set. These
groups are not as tightly clustered as was apparent in previous LDA plots, probably because
the data are not so significantly different from each other. Nonetheless, if the data for these
groups are removed and the data replotted all remaining groups separate (Figure 4.25B). The
relative lack of cohesion of the groups representing the final data sets (Groups 7, 8, 9 and
10), is obviously expected as they are essentially all black ballpoint pen inks from the same
brand and made in the same country. However, it is still apparent that the batches can be
distinguished from each other which is extremely encouraging as it strongly indicates that

each batch of inks can be uniquely identified and that terms of LDA plots in the analytical and

Having established that it is possible to uniquely identify a selection of blue ballpoint pen inks
made in France, fifty black ballpoint pen inks (ten batches each of five samples) made in
Mexico, was investigated. Interpretational data are reported in Figures 4.32 and 4.33.
It was extremely difficult to find ten supplies of the same brand of ballpoint pen ink made in
Mexico, however, two individual scientists on two different trips to the country some five
months apart (Groups 1-4 and Groups 5-10) made the purchases and consequently it is
logical that, while there may be some overlap of batches that could not be established, at
least ten different packages of ballpoint pens were obtained on different occasions and can
therefore be used to confirm that there was little or no bias in sampling procedures used in
this study.
From the data detailed in Figure 4.26, it is obvious that there is one group (Group 4), that
stands completely apart from the other nine groups. The other groups from three other
separated clusters in the LDA plot (Figure 4.26) essentially representing in Groups 1, 2 and 3,
the remaining batches of ballpoint pens purchased by scientist one, while the remaining five
groups of samples, purchased by scientist two, from two other isolated groups. In order to
determine if these groups can be further separated, an additional iterative LDA plot was
undertaken having first removed all data associated with Group 4 samples (Figure 4.27A).
From this figure it is apparent that seven of the nine groups can easily be identified and from
well associated clusters in the LDA diagram (Figure 4.27A). However, samples from Groups 8
and 9 still appear to cluster closely together even though they can actually be distinguished
from each other. Consequently, it was necessary to replot the data having first removed
seven of the nine groups of samples. When a replot of the remaining data was undertaken
(Figure 4.27B), all three groups are easily separated and formed tight clusters within the LDA
plot (Figure 4.27B). From these plots (Figures 4.26 and 4.27), it is obvious that all individual
samples cluster well into their respective groups and that all batches can be identified
unambiguously.

The final set of ballpoint pen inks that was investigated in this preliminary study was a series
of red BIC Crystal Ballpoint pen inks from China. Unfortunately, it was only possible to obtain
six packets of these pens during a single visit to China. However, the data were treated in the
same manner as for the black and blue ballpoint pen inks and the resulting LDA plot (Figure
4.28) shows that again the individual samples within the groups are extremely closely
associated and that essentially all six groups can be distinguished from one another.
From the data that have been used to develop Figures 4.18 to Figure 4.27, it is obvious that
all the ballpoint pen inks in this study can be classified into their correct manufacturing
groups and that individual colours of ink, manufactured in a specific country by a specific
manufacturer, have a very significant probability of exhibiting a similar generic elemental
signature.

4.3 Fountain Pen Ink
4.3.1 Effect of Sample Size on Reproducibility of Fountain Pen Ink.
Seven different inks were used in this study. The description of samples used in this study is
detailed in Section 3.3.3.3 and Table 3.9). Sample preparation and dissolution techniques for
this experiment have been described in Section 3.4.3.1. Data are detailed in Appendix 2;
Table 5 and statistical data are detailed in Appendix 3 Tables 1-5. While it is obvious that
when checking ink on documents a significant amount of ink will not be available, this series
of experiments is designed to establish the elemental distribution patterns in any reference
bulk ink that may be available and to have that as a reference for comparison of inks on
paper. In any analysis it is recognised that the nearer the detection limit the data is the less
robust and more imprecise it also is, consequently it is first necessary to establish whether or
not small quantities of ink could be used to provide accurate data in the case of establishing a
reference sample with which to compare any recovered ink to. In this experiment, four
different volumes of ink (20, 50, 100 and 200μL) were trialled to establish if, for example, a
single drop of ink (approximately 100μL) could provide a reference trace element signature.
Because the ink “hangs up” inside the pipette tips of the micro syringes used, which if only
volumes were used would lead to imprecision in the final data, the mass of each ink sample
used was also determined to four decimal places. Initially, two fountain pen inks (Black Parker
samples 187-198 made in France and Blue Schaeffer samples 247-258 made in Slovenia)
were selected for this investigation. Samples were taken in triplicate.
When data were plotted graphically (Figures 4.29A and B), it was found that the elemental
concentrations were exceptionally reproducible for all volumes/masses of ink used. The only
“exceptions” were analytes below concentrations of a few ngL-1 in the ink and this essentially
means only some of the more “heavy” rare earth elements. Analytes with concentrations
above 1μgL-1 all had excellent reproducibility.
From the data detailed in Figures 4.29A and 4.29B, it is apparent that the elemental
signatures of the two black fountain pen inks, made in two different countries, are
significantly different and that they could obviously be uniquely identified. However, in order
to confirm this observation, and to also confirm that the same reproducibility of a trace
178
element signature could be achieved with different bottles of ink, an additional experiment
was undertaken using a second bottle of Shaeffer black ink made in Slovenia, a second bottle
of Shaeffer blue ink made in Slovenia and two new (different) bottles of Shaeffer red ink also
made in Slovenia (Appendix 2 Table 5). The two bottles of red ink were bought together in
the same store.
The data for the eight different bottles of ink were plotted together using the same LDA plot
(Figures 4.30 A to C). The elements used and the description of the inks are included in the
diagram. In Figure 4.30A, only two groups of samples (Groups 1 and 5; black Parker ink from
France and blue Shaeffer ink for Slovenia respectively), could easily be separated.
Consequently, an iterative approach was again introduced and the data for these two groups
removed before replotting the remaining data for the other six groups using a separate LDA.
In this plot (Figure 4.30B), only Group 4 and 6 samples (the second bottle of Shaeffer black
ink from Slovenia and the second bottle of Shaeffer blue ink also from Slovenia respectively),
formed discrete separate sub-groups. This left four bottles of ink with still overlapping each
other. These inks are Groups 2 and 3 (Parker blue ink from France and Shaeffer black ink from
Slovenia respectively), which is unusual and the two bottles of Shaeffer red ink from Slovenia,
bought in the same store at the same time. These latter two samples are impossible to
separate and it is highly likely that, as they were purchased together at the same store they
come from the same order from the store and are from the same batch. This makes things
extremely interesting as if this is the case then it confirms that it is not possible to separate
inks from the same batch of manufacture and significantly strengthens the suitability of the
technique as a forensic investigational tool.
In an attempt to split the data from the two red ink samples, a third iterative LDA plot was
undertaken using sample Groups 2, 3, 7 and 8 (Figure 4.30C). In this plot it is now apparent
that Groups 2 and 3 inks are easily identified while Groups 7 and 8 still are inseparable.
Throughout the entire series of these LDA plots it has been quite apparent that the data
representing the individual groups of samples (albeit within groups they are simply repeat
analyses of the same ink using different volumes) cluster extremely closely together. This
adds significantly to the assertion that the analytical methodology is extremely reproducible
and that the differences between bottles of ink, possibly representing manufacturing
179
batches, are real. The latter point is further emphasised by the almost exact reproducibility of
the two elemental signatures from the Shaeffer red ink manufactured in Slovenia.
4.3.2 Comparison of the Elemental Signatures of Brands of Fountain Pen Ink
Having established that it was theoretically possible to identify the signatures of individual
brands of fountain pen ink, a further thirty five bottles of ink were purchased from around
the world to verify this initial assumption. Each sample was analysed three times and 200μL
of sample were used as the analytical volume. The masses of each sample were also taken
and used as the definitive parameter when determining the concentrations of all analytes
(the use of a micropipette was simply a convenient means of introducing roughly the same
mass/volume of ink). Data for this investigation can be found in Appendix 2 Table 6.

The data for each colour ink was investigated using LDA. Initially data for sixteen different
black inks were plotted using a single LDA (Figure 4.31A), and because there were only three
replicates of each ink it was decided not to use validation samples in any of these plots. This
removal of validation samples does not compromise the interpretation of data as all
replicates plot extremely close together confirming the reproducibility of the analytical data.
In Figure 4.31A, nine groups, Groups 2, 5, 7, 11, 21, 23, 25, 30 and 34 all plot as separate
distinct groups, while seven groups, Groups 8, 13, 14, 17, 19, 28 and 32 are not easily
separable. Consequently, it was necessary to undertake an iterative approach to separation
and re-plot an additional LDA with the separable nine groups of data removed (Figure 4.31B).
Again, after this iteration it was possible to separate all but four of the remaining groups and
it was therefore necessary to plot a second iterative replot of the LDA (Figure 4.31C) to
confirm the separation of all black ink groups in this study. From these plots it is apparent
that all the black fountain pen inks (16) in this study could be separated from each other and
back to individual bottles of ink.
The same approach was undertaken when investigating whether it was possible to distinguish
between sixteen bottles of blue fountain pen ink using their trace element signatures. Using
data for all these samples to plot an LDA (Figure 4.32A); it was apparent that only four groups
(Groups 9, 10, 15 and 22) could be easily distinguished. When data for these groups were
removed and a second LDA plotted using the data for the remaining samples (Figure 4.32B),
all groups with the exception of Groups 1, 29, 31 and 33 could be individually identified. It is
interesting to note that these four groups represent Pelican ink manufactured in Germany
and three different brands of ink (Camel, Parker and Chelpark) manufactured in India. This
observation leads to the possibility that inks for different companies could be being produced
in one country and simply re-bottled prior to sale.
When data for groups 1, 29, 31 and 33 were replotted using a third LDA, it was easy to see
that Group 1 samples formed a distinctive separate group but that the three remaining sets
of data (blue ink made for Camel, Parker and Chelpark in India) still remained closely
associated adding further to the concept that a single supplier of ink could distribute their
products to a number of different outlets with the initial ink being rebranded before sale.

Figure 4.33 LDA Plot of analytical data for four different bottles of red fountain pen ink.
To a large extent this is a problem as the purchaser would obviously be paying a premium for
a specific brand of ink and therefore be wasting their money on a brand name and not on a
better product.
The final series of red fountain pen inks was also investigated. However, in this case only four
samples were able to be purchased. Nonetheless it is still valid to determine if it is possible to
differentiate between the trace element signatures of these four brands. The discrimination
between these four red inks should be relatively easy as the inks were supposedly
manufactured in four different countries. When the data are plotted as an LDA plot (Figure
4.33), it is quite obvious that separation of the four groups has been achieved and again that
the reproducibility of data is excellent with really no discernible scatter of replicate points.
The same analytes were used to construct Figure 4.33 as previously used for Figures 4.31 and
4.32. From the data detailed in Figure 4.33 it is, as expected, relatively simple to distinguish
between the four red inks studied, however it is anticipated that if more inks had been
available it would have taken a number of iterative LDA investigations to unambiguously
identify the individual makes.

This investigation has been able to essentially prove that it is possible to identify batches and
manufacturers of fountain pen inks. However, the possibility of also finding a generic
signature for inks made in the same country but ultimately sold under different brand names
has been raised and therefore has to be investigated. To undertake this investigation average
values for each individual fountain pen ink thus far investigated were produced and data
compared using a Comparability Index Plot to establish to what extent any of the trace
element signatures of the inks compare between brands.
From the data presented in Figure 4.34A where a single Indian ink has been compared to the
remaining ink samples in the data base, the trace elements signature indicates that there is a
significant degree if comparability between all Indian inks. The most interesting aspect of this
plot is that there is a single Waterman Black ink (Sample 36 in Appendix 2 Table 7), made in
France, that appears in the middle of the Indian data. This could easily imply that this ink was
made in India and then sold in France as being made in France. The making of inks in India is
easily understandable as the cost of labour in that country is significantly less than in the
more Westernised countries of Europe. There is a significant break in slope detailed in Figure
4.34A. The significance of this break is that all samples coming after the break are unlikely to
be associated with the same generic signature of those before. The corresponding drop in
the comparability index percent from 94.04 to 79.28 is also extremely significant and strongly
indicates that any ink occurring after the break is in no way associated with the generic
elemental signature of the inks before the break. Again, this is extremely interesting as, apart
from the one French ink in the initial data before the break in slope, all the inks on the initial
data set are made in India and no Indian ink occurs after the break in slope.
In Figure 4.34B, the data for a German made ink, Pelikan Black, is compared with the data for
the data set of the remaining ink samples. In this graph, the initial break in slope is not nearly
as pronounced as it was in Figure 4.34A. This indicates that there can be some degree of
overlap of populations before and after the initial break in slope. The data seem to indicate
that Pelikan, Cross, Lamy and Graff von Faber Castell black inks all have a significant potential
of being made by the same manufacturer and only bottled and sold with a “theoretical
manufacturers” mark on the bottle.
188
Based on that observation it could be suggested that all these brands of black ink are made in
Germany, with the manufacturer being the same for all four. Obviously, all the inks can be
identified at batch level, as has already been determined. However, if there is indeed a
generic signature in the inks (as appears to be the case in Figure 4.34A), then it is equally
possible that these four “manufacturers” can be simply making varying amounts of profit on
the basis of the “name” on the bottle rather than anything more special in the ink itself.
Perhaps it is naïve to assume anything different in the first place.
The second break in slope in Figure 4.34B comes at a point beyond which there is essentially
no significant probability that the inks after this point have any relationship whatsoever with
the initial sample even though the comparability index is above 95%.
From the data detailed in this section it is apparent that, using elemental fingerprint patterns,
it is possible to distinguish between different batches of the same colour inks. However, it is
apparent that generic elemental fingerprints can be used to determine similarities and
differences between inks, the extremely high probability that inks are bulk manufactured in
specific countries around the world and shipped to different “branded” companies where
they are re-labelled and rebottled with that company’s specific brand and then resold as if
they were manufactured by that company. This means that country of origin is difficult to
determine unless reference data bases of inks that can be 100% guaranteed to come from a
specific manufacturer, in a specific country, can be constructed and used. Nonetheless, by
using the elemental fingerprint of an ink there is an extremely high probability of determining
whether or not the same batch of ink has been used to produce marks on a document and
whether or not the marks on a document are made with the same batch of ink as is present
in a reference bottle or ink cartridge.
4.4 Pencils
4.4.1 Analytical Technique
Analysis of the pencil lead samples following a dissolution procedure was not considered
appropriate as it was not possible to remove pencil lead debris from paper by scraping
189
without entraining a considerable amount of paper into the final sample. Consequently, any
scraped paper could not represent the pencil lead used and therefore could not be related
back to the dissolved pencil lead sample. Therefore, all pencil samples were analysed using
Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA ICP-MS) only. The
analytical methodology is detailed in Section 3.1.3 and sample description is detailed in
Section 3.3.4 and Table 3.11 and 3.12. Data are detailed in Appendix 4.
4.4.2 Samples
Five different brands of pencils of three different hardnesses, manufactured in a combination
of nine different countries, amounting in total to 97 individual pencils plus an additional five
samples from each of three boxes and three samples from each of an additional five boxes of
pencils were used in the initial reproducibility study. Analytical data from all experiments in
this section are detailed in Appendix 4, Tables 1-2.
4.4.3 Analytical Reproducibility.
Three boxes (12 pencils in each box) of PaperMate 2B pencils were chosen for the
preliminary reproducibility study (Appendix 4 Table 1 boxes 1-3 inclusive) and an additional
five boxes of 2B pencils were chosen as a validation study to confirm reproducibility data
initially determined (Appendix 4 Table 1 Boxes 4-8 inclusive). All data produced are expressed
as counts per second and no data have been normalized to an internal standard as there was
no absolute or known concentration analyte available that had a standard concentration
throughout all the pencil leads. The interpretation principle of inter-element association
pattern recognition is based on the fact that internal standardization is unnecessary as it is
the relationship between all the analytes that determined the “fit” of the data and not the
absolute concentrations of analytes.
When the results for samples taken from boxes 1-3 inclusive are compared (Figure 4.35), it is
obvious that the analytical data are extremely reproducible and that the trace element
signature of each of the five pencil leads in each of the three boxes of pencils appears
generically similar. Of the three sets of data the data from the pencil leads bought in Australia
show signs of a greater degree of variation than the pencil leads in the other two boxes.
190
However, even this set of data could not be said to have significant differences between each
of the components (Appendix 4 Table 1).
In order to confirm the similarities and differences between the sets of data, the average CPS
data for each of the three boxes of pencils is calculated and plotted together (Figure 4.36A).
From this diagram it is apparent that the boxes of PaperMate 2B pencils, bought in the UK
and China both appear to have similar generic trace element signatures while the equivalent
box of pencils bought in Australia has a different trace element signature with element CPS
data appearing lower for the majority of the analytes. This observation is important because,
while the differences between the trace element signatures of pencil leads from different
countries may be a reflection of batch number, the similarities between the signatures may
lead to confusion in assigning specific provenance as if trace element signatures appear the
same for the same batch the fact that one batch was bought in the UK and the other in China
could easily be a source of an alibi. If these closely related signatures cannot be distinguished
between there may be a significant provenance establishment problem.
Consequently, an LDA plot was produced to represent all fifteen pencil leads (Figure 4.36B).
In this plot, it is apparent that the three different boxes of pencils form into three distinctive
and unambiguous sub-groups and that their validation samples are associated correctly with
each sub-group. Therefore, while there is a close association of the PaperMate 2B pencils
sold in the UK and China (Figure 4.36A), using an LDA plot it is easily possible to distinguish
between them with no ambiguity whatsoever (Figure 36B).

On the basis of the initial reproducibility study it can be confirmed that the comparability of
pencil lead data from an individual batch appears to be excellent and it is therefore possible
not only to confirm that the reproducibility of the LA-ICP-MS technique is excellent and
entirely suitable for this type of investigation, but also that batch to batch identification, and
consequently batch specific provenance determination for pencil leads, also has a high
degree of probability of being forensically viable. Furthermore, it is also probable that a single
pencil mark can be traced back to an equivalent pencil with a very high degree of probability
and little to no chance of a false positive or false negative result (Figure 4.37).

4.4.4 Differences in the Elemental Fingerprint of Different Pencil Brands of Different
Hardnesses and Manufactured in Different Countries.
This study was designed to investigate the possibility of using trace element inter-
relationships to determine country of origin of pencils. While pencils are not generally used
for signing documents in day to day activities, and documents signed in this manner are not
accepted as legal because pencil marks can be easily removed and written over, they are
nonetheless a significant part of the falsification of documents and as such are included for
completeness sake.
A total of 97 different pencils were used in this study. The samples are grouped according to
two categories of hardness HB and 2B (Appendix 4 Table 2), and although it was ultimately
determined that the majority of the HB pencils used in this study were manufactured in China
(China (40 pencils) and Mexico (21 pencils)), they were sold by four different suppliers in
three different countries. The data for the HB and 2B pencils are plotted together (on the
same LDA graphs) because if there was a generic similarity between countries this would
show up as a close association of groups on the plot (Figure 4.38). In this diagram, it should
be noted that while Groups 7 and 8 were both manufactured in China, but pencils included in
this group were bought in Australia (Group 7) and the United Kingdom (Group 8)
independently. Consequently, it is deemed appropriate to subdivide the data for these two
“groups” into two sub-groups before plotting.
From the data detailed in Figure 4.38A it is apparent that, when data are subjected to LDA,
there is both co-association and separation of sample groups. However, while Groups 3 and 8
appear to cluster quite strongly together (Figure 4.38A), and Groups 1 and 4 cluster, albeit
slightly less closely, there is no obvious generic reason for them so to do as they are
theoretically made in three different countries and the “clusters” contain data from both HB
and 2B pencil leads. Consequently, it is necessary to undertake an additional iterative LDA to
determine if this clustering reflects a generic co-association of elements superimposed into
the pencils during manufacture or not. In order to establish whether or not the initial
groupings can be verified, it is necessary to undertake a further iterative LDA on a reduced
data set. Therefore, the data for Groups 2, 5, 6 and 7 were removed and the data for Groups
195
1, 3, 4 and 8 replotted (Figure 4.38B). In this plot (Figure 4.38B), it is quite apparent that all
four replotted groups can be easily separated and each forms a distinct separate cluster of
data with validation samples plotting in the correct group. Consequently, it appears that
again, the separation of samples is associated more with production batch and far less with a
specific manufacturing process or country of manufacture. This aspect further validates the
ability of the LA-ICP-MS technique to provide definitive data sets that can be used in accurate
data interpretation initiatives.

4.5 Differentiation Between Ballpoint Pen Inks on Paper using LA-ICP-MS.
4.5.1 Introduction
Determining the chemical composition of ink that has already been transferred to paper, i.e.
a signature on a document is often extremely difficult. Generally, some form of
chromatographic separation is used to determine the composition of the ink involved and the
resulting chromatogram is compared with that of reference inks to achieve a match.
However, it is necessary to first remove a sample of the ink from the paper it is on before
analysis can proceed. This process can be extremely difficult to achieve without “damaging”
the document, especially if any significantly sized sample is required to achieve accurate
comparison. Additionally, basic chromatography of the ink may yield a result that does not
separate the ink of use from that already present on the paper as the organic components
that make up the ink signatures are often generic and cannot easily be distinguished from
one another. In addition, the mass of ink available for testing is extremely small and there
may not be sufficient to determine unambiguous differences even if a large part of the
sample is used. In here is another problem in that removal of material from a document for
testing is an aspect that every forensic scientist seeks to avoid. Consequently, a methodology
that does not remove the sample from its original matrix and, to a very large extent, is non-
destructive, would be an important addition to the forensic arsenal of every document
examiner.
The ability of LA-ICP-MS to only require extremely small samples to achieve accurate analysis
of a wide variety of analytes makes this technique really appropriate for the analysis of inks
on paper samples. The technique is almost 100% non-destructive and consequently is even
more universally acceptable in forensic document examination as even though sample is
consumed during analysis the mass of material is so small that it requires a microscope to see
what has been destroyed. Results detailed so far on this thesis with respect to solution
analysis using ICP-MS, indicate that the basic technique is capable of rigorous and extremely
accurate specification of individual batches of paper, ballpoint and fountain pen ink and
pencil marks. However, the problem remains as to how this technique could be used to
determine the elemental signature of inks that have actually been deposited on paper.
197
If it was possible to use LA-ICP-MS to differentiate between blank paper and paper on which
ink has been deposited without having to remove the ink this would be an extremely useful
breakthrough and a significant step forward in identifying differences between inks used to
forge or modify documents. The technique, used in association with luminescence data,
chromatography and graphological analysis, could then be used to give an indication of the
batch of paper and of ink used and serve to unambiguously provide evidence to ensure that
false positives and false negatives, generated as a result of the often extremely limited
sample mass available for analysis, could be ruled out of an investigation.
What is more is that if the technique of LA-ICP-MS was as specific in identifying inks and
papers as it appears to be able to be from the preliminary research on the separate matrices
using solution based ICP-MS, it could be used to identify these materials and trace them back
to actual sources thus eliminating any ambiguity there could be of identifying provenance of
the materials and identification of persons of interest.
4.5.2 Preliminary Study of Ink on Paper Analysis using LA-ICP-MS.
Initially it is extremely important to be able to prove that the paper on which ink has been
deposited is uniform in its trace element distribution parent across an individual sheet. This
aspect has been studied in Chapter 4, Section 4.1 and conclusively proven. In addition, and
possibly the most important aspect is that if a laser ablation traverse is run across an ink mark
then the trace element profile across that mark is as near as possible uniform. The reason for
this is that unless the signature of the paper and ink:paper combined is uniform identification
of the components of each and tracing those signatures back to original batches of paper and
ink will be extremely difficult. This will be made even more difficult if the document is of
historical importance or is in any other way precious and cannot be destroyed, even partially,
to obtain a paper blank. Consequently, a number of ablation lines were run across various ink
marks on sheets of paper to determine if differences were significant and related to analysis
position on the paper. An example of a typical data traverse line is detailed in Figure 4.39.
From this figure it is apparent that while there are small differences across the ink mark,
largely associated with inclusions of dust etc. in the paper or incorporated in the ink when in
use, largely the elemental signature across the ink mark is uniform.

4.5.3 Reproducibility of the Elemental Composition of Ballpoint Pen Ink on Paper
Based on the uniformity of elemental profiles across ink marks it was decided to establish the
robustness of the procedures used and the precision of analytical data obtained using this
method for three different types of paper and nine different inks. Initial studies of laser
traverses on the paper and knowing the concentrations of elements in the various inks
studied made it appropriate to identify the most realistic analytes that could be used for this
study. Many of the analytes present in paper and ink were in concentrations that were at or
near the detection limits for solution based ICP-MS techniques and consequently would be
below the detection limits for LA-ICP-MS techniques. Consequently, a final list of appropriate
analytes was chosen and is detailed in Table 4.7.

A description of the inks and paper used in this study is given in Appendix 5. Each ink was
applied on three different paper samples, paper sample one (Double A premium: Thailand),
paper sample two (Reflex Recycled Pure White: Australia) and paper sample three (Paper
Time scale representing 90 seconds and a distance of approximately two millimetres
199
One Premium Presentation: Indonesia). Nine different ink samples were applied in replicates
of six to each of the paper samples making a total of 180 samples in all. In addition, paper
analytical blanks were determined in replicates of six for each of the three paper samples
used. The inks used were: blue, black and red BIC, blue black and red PaperMate and blue
and black Officeworks, and red J.B. An individual single line was drawn on a single sheet of
paper for each sample. Sixty sheets of each different paper were used and data represent LA-
ICP-MS analysis of each if these lines. Data were accumulated in “Time Resolved” mode.
However, it was considered analytically incorrect to accept computer software interpretation
of the data using Glitter™ as inclusions were not able to be identified using this software. In
the event that inclusions occurred, the resulting data, if interpreted using Glitter™ would be
inaccurate and lead to incorrect data being produced. Consequently, data for each analyte
for each sample were examined by the analyst and calculations of the CPS data made on the

basis of reviewed interpretation between the analyst and supervisor, a process taking
approximately two hours for each scan. Analytical data are detailed in Appendix 5 Table 1. A
blank correction for each paper was made for each scan and the resulting elemental
fingerprint (trace element association pattern) for each of the ink samples has been compiled
in Appendix 5 Table 2. Trace element signatures for cross sections of each of the inks studied
are detailed in Figure 4.40. Once background subtraction of the paper has been undertaken
there are some values that are less than zero. This is because variations in high values for the
background for any specific paper may, when averaged be above the values that are reported
for the paper:ink signal. In all cases these numbers have been given a value of 1CPS in
Appendix 5 Table 3.
The data detailed in Figure 4.46 confirms that the reproducibility of the ink signatures is, in
the majority of cases, the same for all six repeat analyses of the same ink. Major differences
usually only occur where the concentrations (in terms of counts per second (CPS)), are at or
close to the detection limits of the technique which is approximately 100CPS for all analytes.
Detection limit in this thesis is defined where the coefficient of variation percentage is
greater than 50% relative. Data detailing the coefficients of variation for all inks on all papers
studied are detailed in Appendix 5 Table 3 to give an idea as to how confident the analyst can
be in the data provided.
Unfortunately, it is not possible to cross compare the solution data for an ink with laser
ablation data for the same ink on paper as response characteristics for the same element
using the different techniques are entirely different. Consequently, it is necessary, when
tracing back an ink to a specific pen, that a mark on paper is made using that pen, must give
reproducible results, and it must be statistically realistic to be able to accurately compare the
trace element profiles of individual inks with the mark being investigated to be able to
eliminate inks that do not match the profile of the one being investigated. Therefore, the
most important aspect of this type of investigation is that the trace element association
pattern should be the same for the same ink on different sorts of paper. In this way a number
of suspect pens can be used to make a mark on a reference piece of paper and the blank
subtracted data obtained used to compare with the results obtained by the reference ink on
202
a completely different sheet of paper. This may seem an obvious observation. However, it
has to be remembered that the background contribution of the elemental values for the
paper blank, to the paper:ink combined elemental profile, may be relatively very and as such
the resulting blank corrected ink elemental profile stands a chance of being either
overcorrected or under-corrected and consequently blank subtraction may lead to a final
data set for an individual ink being less precise than could be hoped for. Under these
circumstances cross comparison of reference inks to an investigation ink sample may be less
robust than hoped for and it is therefore essential to obtain the best results possible for all
analyses. This is especially difficult for this type of analytical protocol as laser ablation is not a
quantitative e technique and even between samples there can be different ablation and
ionization conditions giving rise to variations in the CPS data for each analyte. It is therefore
essential that an experienced analyst interprets all data at all stages. This is especially true of
the use of patented software to “normalize” the resulting time resolved scans, and it is the
author’s opinion that normalization must be undertaken personally by the analyst before a
valid cross comparison can be expected.
Consequently, a detailed investigation was undertaken into the comparison of corrected
elemental profiles for the inks studied when deposited on all three papers. Each data set for
this study are detailed in Figures 4.41 – 4.45.
Initially the reproducibility of the individual inks was investigated. Three different blue inks
contained in three different manufacturer’s pens were used for the initial blue ink study.
Each ink was used to mark a single line on six different sheets of paper from each of three
different manufacturers. The blank paper corrected results are plotted in Figure 4.41A-C.
Each of the three diagrams in Figure 4.41 confirms that the element plots exhibit a
remarkable degree of comparability for each ink and the three different papers. This of
course was to be hoped for but was not expected as each paper type has a different
elemental signature leading to different background subtraction data for each paper. From
the data, it is also apparent that BIC and Paper Mate blue ballpoint pen ink have a relatively
similar signature to each other while the signature for the Office Works ballpoint pen ink is
somewhat different. This backs up the solution data already detailed. As mentioned
previously, it is not possible to compare the quantitative data for solution work with the
203
qualitative data for laser work. Nonetheless it is quite obvious when comparing the data from
the laser work that the signatures are very similar and the inter-elemental relationship
patterns, on which the principle of elemental fingerprinting is based, are extremely robust.
The same procedure is undertaken for black inks (Figures 4.42A-C). However, in the case of
these inks there are more analytes that do not have good reproducibility than in the case of
the blue inks. Notable amongst these analytes are Mg, Rb, Cr, Mo and Zr. With one notable
exception, Mg in black Paper Mate ink on paper 3. This is because the value of the blank for
paper 3 is approximately ten million CPS and the value for the combined paper:ink signal is
very similar, also approximately ten million CPS, leading to a wide variability of the corrected
ink signal(ten to fifty thousand CPS or 0.5% relative residual) when the background is
removed.
Nonetheless all three black inks on the three different papers have a characteristic analyte
fingerprint which appears, even with visual inspection, to be different for each of the inks.
The black Office Works ink (Figure 4.42C) has an analyte fingerprint that appears to be much
more precise than the other two. However, the concentrations of analytes in this ink are
considerably higher than in the other two inks and consequently background correction does
not have such a significant influence on the final data for the ink. This aspect has to be
remembered when interpretation of data is required and it again worth noting that the
interpretation of data should also be undertaken by an experienced analyst who is trained in
this sort of work for the results to be valid.

The final set of inks to be investigated was red in colour. In this case it was not possible to
have the same three brands of ink as those for blue and black inks. Nonetheless three
individual manufacturers’ pens were used to obtain the data on the same three different
varieties of paper. The data for this series of experiments are given in Figure 4.43A-C. The
data in these figures would appear to be less precise than data for blue and black ballpoint
pen inks, probably because the values for the CPS data are also lower and, as detailed
previously, blank correction forms a very significant reduction in the overall combined
paper:ink LA-ICP-MS values. Obviously, it would be preferable if only the ink could be
analysed using LA-ICP-MS and there was no incorporation of any analyte signal from the
paper. However, this is not possible with the current equipment as the laser crater is over
50μm deep and will penetrate the paper. Future generations of lasers may be able to be
controlled better and not add so much of the paper signature to the combined signal.
Nonetheless, it is quite obvious from the data detailed in Figure 4.43A-C that each red ink
gives its own individual trace element pattern (fingerprint) and as such can be recognised
from the other two inks. However, what is represented in Figures 4.41 to 4.43 is a graphical
representation of the data and interpretation is therefore subjective. This approach is not
really acceptable in a court of law and therefore it is essential that a statistical or
chemometrical interpretation is applied to the data to determine if the values obtained can
stand up to rigorous scrutiny and can still be interpreted and classified accurately. In order to
achieve this LDA plots were undertaken of all the data (Figure 4.44A-C), initially of each
colour of inks separately and finally all samples of all inks together (Figure 4.45 A and B). Even
though the colours of inks can be easily differentiated by eye, it was felt necessary to
compare all the study inks analysed together as in some instances the lack of ink on a
questioned docuemtn may lead to confusion of colour and in some cases there may be some
comparability of an elemental profile related to generic similarities in a country of origin or a
mnufacturer not yet studied. In this event it would be essential to ensure that any colour ink
could be used in the statistical cross comparison and still result in accurate apportionation of
the evidence ink with that for a reference data base sample.

209
As can be seen from the data in the three LDA plots (Figure 4.44A-C), all samples of all the
inks separate perfectly into their relevant sub groups and all validation samples compare
exactly with their equivalent groups. This result indicates that the technique and
interpretational protocols have an extremely high probability of being extemely useful in any
document based forensic investigation.

The data further confirm that if an ink mark is made on a document it is possible to develop a
reference set of marks from a wide range of different ballpoint pen inks on another
document and subtract background counts from the paper of the documents that have been
quantitatively obtained using LA-ICP-MS to give an elemental association pattern signature of
the original inks that can be accurately compared using LDA. This conclusion indicates in the
strongest terms that LA-ICP-MS analysis and LDA interpretation of ballpoint pen inks is at
present an embryo technology for document examination that has significant possibilities in
this area of forensic science and crime scene investigation.

Chapter 5 Conclusions and Recommendations 5.1 ESDA
Since it was first developed and introduced as a device for detecting indented impressions in
England in 1978, the role and operation of ESDA in Forensic Science has been extensively
studied and researched by scholars and forensic scientists all over the world.
The current study, into the possibility of modifying the ESDA technique and extending its
useful application range, is designed to highlight the need for, and provide a methodological
contribution to, an overall change in the forensic investigational approach to the study of ink
and pencil marks on paper, and is meant to provide a rational new approach to the science of
document examination using ESDA in combination with chemical solution based analysis of
the various components present in these types of investigations and LA-ICP-MS analysis of
original material, where “destruction” of the paper or marking material is not allowed.
Data produced using the ESDA are extremely sensitive to paper grade and variations in
ambient humidity. It was established that the paper quality on which the ESDAtesta process
was conducted could significantly influence the quality of the ability of the ESDA to produce
results. The strongest ESDAtesta indented impressions were obtained on the heavier grades
of paper, in particular 110gsm paper and less so in the lower gsm papers.
The results detailed in this thesis also indicate that humidifying the document, on which the
ESDAtesta impressions have been made before the ESDA process was conducted, could also
affect the quality of the ESDA results. It was found that humidifying the document for a
period as short as three minutes could significantly reduce the intensity of the developed
ESDAtesta indentations and therefore limit the ability of the investigator in unambiguously
distinguishing marks. This is a somewhat controversial conclusion and it is obvious that as this
“ambiguity” in the generally “recommended” protocol has now been highlighted, there has
to be significantly more investigation into this aspect before a definitive protocol for the use
of ESDA can be promulgated and the technique made routine.
211
In addition, applying low <40oC heat to the document can improve the visibility of the
indentations. However, temperatures above this, where the document is exposed to
temperatures at which the cellulose itself could become denatured (>200oC), cause changes
in the paper where the eventual ESDA image will become progressively unsatisfactory until at
temperatures above 400oC, when the paper becomes significantly carbonized, the image
becomes impossible to read as the paper is impossible to place on the ESDA test bed without
breakage and crumbling. However, it has been possible to obtain decipherable ESDA images
from paper that has been partially carbonized at temperatures below 300oC.
While it is obvious that the ESDA based system of investigating the nature of marks on paper
may be used to determine their written content, it is also necessary to be able to determine
whether or not a particular mark was made by a specific writing implement. In addition, there
would be a considerable advantage to a document examiner if it was possible to trace the
composition of the inks or pencils used to make that specific mark back to an individual brand
of pen or ink or even to an individual batch of ink in that pen. Furthermore, to be able to
trace an individual sheet of paper back to a country of origin, batch of manufacture or even
ream of paper would allow the forensic document examiner to provide a statistically robust
and significant identification of provenance of all the components of a forged document.
5.2 The Chemical Investigation into the Unique Composition of Paper, Ink and
Pencils using ICP-AES, ICP-MS and LA-ICP-MS
The investigation into the provenance determination of paper, ink and pencil leads, detailed
in this thesis, was designed to establish chemically based analytical protocols to solve
problems associated with provenance determination of these components of a questioned
document that would allow the greatest possible preservation of forensic evidence and still
provide unambiguous results.
Investigations into the provenance of paper were able to confirm that the trace element
distribution pattern within single sheets and single reams of paper were statistically
indistinguishable and that individual batches of paper had the same chemical signature. In
212
addition, it was able to be confirmed that Australian paper has a generic signature that can
distinguish it from paper made in other countries around the world. It is strongly believed
that this type of generic signature exists for other countries of manufacture of paper but
insufficient numbers of different samples from other countries need to be analysed before
this aspect can be confirmed.
In addition, paper that has been completely ashed can be traced back to the original paper
and it is therefore possible to unambiguously confirm whether or not ashed papers have or
have not a common chemical signature with un-ashed material that may also be recovered in
the course of a criminal investigation. It is also appears to be possible to determine whether
or not “old-growth” forest has been used to produce paper, which is an extremely important
environmental safeguard for the preservation of indigenous forest throughout the world.
Individual ballpoint pen inks can be chemically analysed to determine their inorganic
“fingerprint” (their inter-element association pattern). This chemical pattern is also
unambiguously associated with a batch of manufacture and can be used to relate specific
pens back to recovered evidence. Although it may appear obvious what colour an ink is by
simple visual comparison, it must be stated that all similar coloured inks are not the same
and determining the individual inter element association pattern of an ink will facilitate
unambiguous comparison to a reference data base of inks with the equivalent colour and
overcome any false positive and false negative identification. Even with the same colour inks
and the same manufacturer, differences in the trace element signatures of the individual inks
occur and can be easily identified. Consequently, an individual ink can be traced back to its
batch of origin or compared with recovered relevant material from the crime scene or from
follow up investigations to determine matches.
While there are obvious differences in the trace element association patterns for individual
batches of ballpoint pen ink, at this stage there appears to limited data that could confirm
the existence of a generic trace element signatures for the same colour ballpoint pen inks
from individual countries.
213
Research into the unique identification of fountain pen inks has confirmed that the chemical
signature of these inks from the same manufacturer and same batch are statistically
indistinguishable. In addition, it is statistically possible to identify batch differences between
inks and to determine the country of origin, and, perhaps more surprisingly, to determine
that some very expensive inks (for example Cross and Pelikan) are made in the same county,
by the same manufacturer and are identical in chemical composition. This aspect identifies
the gullibility of the general public in buying products, not because of their better quality but
simply because they carry a “must have” market brand or some perceived difference, and
also the greed of manufacturers in allowing this deception to take place.
Although it was not deemed sensible to undertake dissolution based analysis for pencil leads,
the use of LA-ICP-MS facilitated just as definitive an identification mechanism. Elements in
individual batches of the same manufacturer have discernible differences on their chemical
fingerprint while there is excellent reproducibility between the chemical signatures of pencil
leads from the same batch. There is also a noticeable difference between the chemical
signatures of different harnesses of pencils form the same manufacturer. It is therefore
equally as easy to robustly identify the chemical signatures of pencil leads and to assign these
signatures to specific pencils or to pencil lead data that have been entered into a data bases.
The fact that pencils are not accepted for signing legal documents means that this research
has somewhat limited use in forensic investigations. However, it does represent a
completeness in the methodology that has been developed to determine the provenance of
hand held writing instruments.
The final proof of usefulness in forensic document examination is the application of direct ink
on paper analysis of documents. In this investigation, a laser was used to traverse across
drawn lines in ballpoint pen ink on different manufacturer’s brands of paper. The data
produced obviously incorporated the trace element signature of the paper and the ink and it
was not a simple matter of blank subtraction to remove the signal of the one from that of the
other to obtain the ink signature Only a limited set of twenty-seven analytes from the sixty-
two determined were present in sufficient concentrations to be useful for determining the
chemical composition of the inks involved in the study. In addition, because of variations in
the background major analyte composition of the paper, due to fillers and dust
214
incorporation, it was necessary to interpret all data manually and to use subjective
(experience) background definition to determine blanks for each analyte in each sample. This
resulted in the manual correction of nearly four and a half thousand data points to obtain the
final data set.
Nonetheless once the data had been obtained, albeit in such a labour-intensive manner, it
was possible to unambiguously identify the individual inks on all the different paper samples,
and to obtain excellent differentiation for each one. This study confirmed that a single
traverse (100μm wide) across an ink mark is capable of providing a chemical signature of the
ink involved and that that chemical signature can be traced back, irrespective of the paper it
is written on, to a unique batch of ballpoint pen ink. This aspect is of major significance to
document examiners as it provides indisputable proof of origin of these types of ink and can
also be used in cross comparison in the case of different pens, even the same brand, being
used to falsify documents.
A combination of the protocols detailed in this thesis add a significant arsenal, to that already
available to the forensic document examiner, in investigations of both falsification and
unique but fraudulent generation of documents, both modern and antique.
5.3 Recommendations
The research detailed in this thesis represents only a preliminary investigation and general
validation of the use of a series of new approaches to document examination and
verification. It is essential that the work be enhanced by future studies that will increase the
statistical robustness of these techniques. These future investigations should include:
• Analysis of more and varied sources of paper, inks and pencils, together with
investigation of photocopier inks (to trace back photocopies to potentially a
photocopier).
• Development and testing of new statistical investigative and interpretive protocols for
potentially more robust provenance determination.
215
• Trialling different varieties of femtosecond lasers to establish if they would be more
capable of producing a chemical signature of pen-ink on paper without as much
incorporation of the paper chemical signature into the initial data signal and thereby
decreasing the need for such complicated and time consuming background correction
measures.
• Development and upkeep of data bases for papers, inks and pencils sin order to try
and establish generic links between countries of manufacture and to identify use of
“old growth” forest pulp in the manufacture of paper.
