A Instrument Description

A1 General

LICO® 100 is a universal colorimeter for liquids suitable for manifold industrial applications. It is easy

to handle and has a sturdy design.

But what is really the reason why objective color measurement of liquids is so important? The human

eye is able to perceive about 100 spectral colors in approximately 100 degrees of brightness and

saturation, which results in about 1 million perceptible shades. Therefore, hues are difficult to describe

by subjective visual comparison.

The specific color of a product is often regarded as a sign of purity and quality, although that is not

necessarily true. Clients often interpret deviations from the shade of an earlier production as defective

product or supply and reject it preventively. In order to avoid such trouble, objective color assessment,

a uniform colorimetric system and reliable instrument are required for production and quality control of

transparent colored liquids.

New Standard EN 1557

EN 1557 (Colorimetric characterization of transparent colored liquids) now also defines color

measurement of liquids on the basis of the time-tested colorimetric standards of DIN 5033. The

principle is to measure the X-, Y- and Z-transmissions. The sample is illuminated with a halogen lamp

corresponding to standard illuminant C. On this basis, Koehler developed the LICO® 100 for exact and

reproducible measurements of transparent yellow-cast liquids.


5

A2 Instrument Design

LICO® 100 measures transmissions of all transparent media. It operates with a halogen lamp

producing standard illuminant C and uses the 2° standard observer as defined by DIN-standard 5033.

A reference beam path compensates measuring values modified by driftings of lamps and

temperatures during operation. Therefore, LICO® 100 provides an excellent long-term constancy and

reproducible measuring results. The universal cuvette compartment suitable for 50 x 10mm square

cuvettes and 11mm round glass cuvettes permits an optimum adaptation of LICO® 100 to the

measurement tasks.

In just one measurement, LICO® 100 evaluates by to the latest ISO-standards giving e.g. Iodine, Hazen

or Gardner values. The basical instrument includes one optional color number with the possibility of

adding-on a random combination of color numbers later or at once. These color systems are

available: Iodine number, Hazen number, Gardner number, Saybolt number and ASTM D 1500 number.

To add-on more color systems later, a program-module-box (bit-box) is supplied. The description of

this bit-box is given in chapter D6.

A3 Instrument Set-Up

Unwrap the instrument carefully and check it for missing parts (delivery note). Please keep the packing

box to pack the instrument safely in case it has to be transported again later.

LICO® 100 should be placed on a level desk surface. The instrument comes with a power supply unit

and adapter for the socket (100 – 240 Volt / 47 – 63 Hz) and is turned on by either pressing the OK-

key or the grey menu key.

Do not turn on and off too fast. Wait for 20 seconds before turning on again not to damage the

electronic or mechanic system of the instrument.

The blue lamp protection cover on the upper left part of the instrument serves to carry the heat off

the lamp and must not be covered.

As LICO® 100 is a sophisticated optical instrument, avoid the following at any rate:

• Do not use the instrument in direct sunlight.

• Do not allow water, inflammable or metallic objects to enter the instrument.

• Do not put filled cuvettes or heavy objects on the housing.

• Do not use the instrument in excessively moist, dusty or vibrating surroundings.

• Do not open the instrument. There are no parts in the housing for the user to check.

• If you have any questions of problems, please contact Koehler’s Technical Service

Department.

A4 Reference Standards

In general, an absolutely transparent medium similar to the sample serves as a calibration or reference

standard for colorimetry on the transmission principle. To measure the color of liquids, distilled water is

filled into a cuvette similar to the measuring cuvette and used as a reference standard. In some

exceptional cases where the density of the substance to be measured differs from that of the distilled

water, calibration is made against a colorless measuring medium. Calibration assigns the reference

standard a transmission of 100% (or Iodine number = 0, Hazen = 0, etc.). As this assignment never

changes, 100 no calibration value needs to be set for LICO®. Instead, just fill a cuvette with the

reference standard and put it into the cuvette compartment to perform calibration.

B4 Battery ModeLICO® 100 can be used with power supply unit or rechargeable batteries. For the latter mode, open

the cover of the battery compartment and insert the batteries as follows:

1. Insert the battery with the switch to the right into the holder until only one contact remains visible.

2. Shift the battery from the left side over the contacts, passing a slight resistance.

3. A beep indicates that the batteries are placed and ready for operation (only when the instrument

is not connected to the mains).

Attention: The contacts must not get into contact with metal or greasy parts.

To recharge the batteries, insert them into the compartment and connect LICO® 100 to the mains with

the power supply unit. We recommend a continuous loading time of 14 hours before the first use. To

exploit the battery capacity best, charge and discharge it always entirely. The display of LICO® 100

informs about the current discharge degree of the battery when the instrument is turned on. When the

battery is discharged, a beep and a display message are given. The message must be acknowledged

with the grey menu key to go on working for a short while. The display message “battery empty” means

that the battery is definitely discharged and needs recharging.

B5 Turning-OffLICO® 100 turns off automatically by a timer function. Manual turning-off is possible, too.

Manual Turning-Off

Press Cursor-Key & in the measuring menu and select option

„Switch Offf“ with the OK-key. Then the instrument turns off.

Turning-Off Via Timer

On delivery, the timer of LICO® 100 is set to automatic turning-off

time of 30 minutes. The automatic turning-off is only active if no

measurement was made within the given period and no cuvette is

in the compartment. The setting can be modified within the tolerances of 10 to 60 minutes.

B6 Photometric PreparationThe photometric preparation requires utmost care, because careless sample preparation is the major

source of trouble, and not the handling of the instrument itself.

Cleanliness is of vital importance in photometry. Therefore, clean the glass cuvettes immediately after

use. Employ only optically perfect samples for measuring. They must be clean and not show any signs

of opaqueness.

Air bubbles in the sample or at the cuvette sides influence the measuring result. They can be avoided

by filling the liquid slowly into the cuvette. Pasty or solid products should be melted and filled-in without

bubbles, if they cannot be measured as they are.

B6.1 Sampling And Sample Preparation

Take a sample from the product you want to measure in accordance with DIN 53242 part 1. Eliminate

turbidities by heating or filtration. Heat partly solid samples before measuring in order to dissolve the

solid share in the liquid one. The preparation must not cause any chemical changes in the sample.

During the measurement there should be no bubbles in the sample.1

• There are several cuvette types available for color measurement with LICO® 100, differing by

material (glass, polystyrene or PMMA2) and path length (11mm and 50mm).

12

• The program calculates automatically Iodine, Hazen, Gardner, Saybolt and ASTM D 1500-

numbers under consideration of the cuvette type employed.

• For the 11mm disposable round glass cuvettes, a dry thermostat is available to warm up to 15

cuvettes to 100°C or 148°C.

C Color Measurement

Whenever the instrument is turned on, a zero measurement is made, taking the empty value (i.e. the

pure transmission values without cuvette inserted) of the optical beam path and comparing it with the

empty value obtained in the previous zero measurement. If the difference between both empty values

is near zero, you can start measuring without calibration. Calibration is only required in case of

considerable deviations of the empty value due to e.g. fluctuations of temperature. The calibration

remains valid until the next recalibration. LICO® 100 features a calibration memory for both path

lengths employed (50mm square cuvette and 11mm round cuvette). If you have to use two different

path lengths, owing to the nature of your samples (e.g. bright samples with Hazen values below 50 or

strongly colored samples with greater Gardner values), it is possible to calibrate both path lengths and

then toggle between them. LICO® 100 uses the corresponding set of calibration data automatically.

C1 Calibration

LICO® 100 features a calibration memory for 11mm round cuvettes and 50mm square cuvettes. To be

on the safe side, calibrate LICO® 100 at least every day. In the calibration, the employed medium is

assigned a transmission of 100% over the whole spectral range. Observe the following rules for

calibration:

• The cuvette type selected for calibration must be identical to the one used for measurement,

otherwise wrong Iodine, Hazen and Gardner values are given.

• Use always clean cuvettes and fresh distilled water for calibration.

Instrument calibration for color measurement

1. Turn-on instrument and printer, if desired. After self-check and

zero measurement, LICO® 100 might ask for calibration. If

LICO® 100 is already on, make sure the cuvette compartment is

empty and press the blue CAL - key. The display reads:

2. Fill a clean cuvette (material and path length to suit your

samples) with distilled water and put it into the measuring

compartment.

3. LICO® 100 detects the cuvette type automatically.

4. Now press the blue CAL - key again to trigger calibration.

5. When the calibration is over and the printer is on, date, time and selected cuvette type are

printed, e.g. :

Then LICO® 100 prompts „Please insert sample cuvette“. Now you can insert your sample cuvette

directly. As soon as you have done so, LICO starts measuring automatically. To calibrate one more

path length, remove the cuvette and press the blue CAL -key again.

Please calibrate carefully to avoid mismeasurements caused

by faulty calibration.

C3 Iodine Number

DIN 6162 defines the Iodine color number as mg of iodine per 100ml of potassium iodide solution.

Color matching by the Iodine number serves to judge the shade depth of clear liquids like e.g. tensides,

plasticizers, resins, oils and fatty acids, whose colors resemble that of an equally layered solution of

potassium iodide. For Iodine numbers less than or about 1, the Hazen number according to DIN-ISO

6271 should be preferred.3 Sampling and preparation are described in chapter B6. A satisfactory

precision of the Iodine value is achieved with a 11mm round glass cuvette.

Measuring procedure

1. Fill the sample liquid into a cuvette and insert it into the

corresponding compartment. Measurement starts auto-

matically.

2. After the measurement, the color value is indicated on the

display.

3. Now press the } -key (DIM) until the Iodine number appears on the display.

C4 Hazen Color Number (APHA-Method)

The Hazen color number (DIN-ISO 6271, also known as "APHA-Method” or “Platinum-Cobalt-scale”)

is defined as mg of platinum per 1L of solution. The Hazen parent solution is composed of 1.246g

potassium-hexachloroplatinate (IV) and 1.00g cobaltous (II)-chloride dissolved in 100ml of hydrochloric

acid and filled up with distilled water until reaching 1000ml. The Hazen color scale serves to determine

the colors of nearly water-clear products. It has a narrower gradation in the light yellow range than the

Iodine scale and reaches even water-clear casts.

Attention:

Samples with Hazen values between 50 and 1000 can be measured with sufficient

accuracy in 11mm round cuvettes.

Hazen values < 50 should be mesured in 50mm cuvettes,

Hazen values < 10 should be measured with the cuvette which was used for

calibration, because nearly water-clear products are susceptible to giving faulty measuring

results due to cuvette tolerances.

C6 Mineral Oil Color Number ASTM D 1500 And ISO 2049

The Mineral Oil Color Scale is used for matching the colors of mineral oil products like lubricating oil,

fuel oil, diesel oil and paraffins. The color scale begins at 0 for water-clear, colorless oils and ends at

8 for very dark brown oils. Visual matching is in steps of 0.5 (0.5 1.0 1.5...). LICO® displays the results

in steps of 0.1. For samples of stronger hue than color glass 8,

color value D8 is displayed.

those of the Hazen scale (APHA). The Saybolt scale begins at +30 (brightest coloration,

corresponding to approx. 8-10 Hazen) and ends at -16 (stongest coloration, corresponding to approx.

350 Hazen).

FF Measurements can be made with cuvettes of 11mm or 50mm path lengths. The greater the path

length, the better the measuring accuracy (50mm recommended).

D6 Program-Module Card (BIT-BOX) of LICO® 100

The program module card (BIT-BOX) permits fast and comfortable updating of the internal software

and an easy extension of color systems. The slot for the program module card is at the rear side of

the housing. The instrument must be off when the bit box installed. Program updates or extensions are

made by inserting the bit box first and then turning the instrument on. Follow the display prompts. Turn

the instrument off after updating and remove the bit-box again. For color number extension, the bit-box

can be used but once.
