The Issue of Purity
Air Liquide does not use low quality raw materials of lower purity, primarily because increased
impurities are known to create application problems such as unidentified peaks on chro-
matographs. We insist on using only the highest purity components available, and stock
more than 800 high-purity components for use in making our gas and liquid standards.
Our Capabilities
The number of possible gas and liquid mixtures consisting of various components in vary-
ing concentrations is nearly infinite. Therefore, this section is only a guideline containing many
of the more commonly requested mixtures we produce. Additional mixtures not shown in
this catalog are available, as are custom developed products for very specialized applica-
tions. Nonetheless, despite being the world leader in specialty gases, we do encounter
certain limitations that preclude production of certain mixtures. Some are safety-related while
most are a matter of chemistry.
Unique SCOTT Technology
The 50-plus year heritage of Scott Specialty Gases, combined with Air Liquide’s century of
gas innovation, equals a rich history of developing proprietary technology to facilitate con-
sistent preparation of the highest accuracy mixtures available in the specialty gas industry.

SCOTT™ Mixtures continued
SCOTT mixtures have long been the definitive standard for calibration accuracy. Our
ISO/IEC 17025 certified laboratories follow strict procedures for preparation and analysis
of gas mixtures, thus ensuring traceable products of the highest quality. When appropriate,
our calibration mixtures are analyzed against benchmark standards such as Standard
Reference Materials (SRMs) obtained from the National Industrial Standards and Technol-
ogy (NIST) or other recognized suppliers such as VSL (formerly NMi) in The Netherlands.
Air Liquide maintains the world’s largest inventory of NIST-Traceable Reference Materials
(NTRMs), which we use in the production of mixtures.
How Gas Mixtures are Prepared, Analyzed and Certified
GRAVSTAT™
Gas mixtures are blended by a number of different methods. The most common method is
to gravimetrically weigh each component of the mixture using a scale routinely calibrated
against NIST weights, resulting in a mixture traceable to NIST. Our GRAVSTAT process yields
results often considered to have less uncertainty than analysis against other reference stan-
dards, which is particularly true for mixtures containing nonreactive components at percent
level concentrations.
Dual-Analyzed Standards
SCOTT RATA Class™ and Compliance Class™ environmental protocol gas mixtures are
dual-analyzed using EPA G1 or EPA G2 methods. Two independent analyses are performed
after the blending process has been completed in order to determine the concentration
for each component contained in the mixture and these analyses must agree to within
±1%. RATA Class mixtures are always directly traceable to metrology institute standards,
yielding the highest accuracy possible and enhancing RATA test performance.

SCOTT™ Mixtures continued
Dual-Certified Standards
SCOTT Reference Class™ mixtures are dual-certified and are the most accurate mixtures for
your calibration needs. They receive two rigorous, independent methods of certification, one
during gravimetric blending using our GRAVSTAT™ process and the other using proprietary
laboratory analytical procedures. Each of these processes yields an accurate concentration
for each component. We then further ensure the accuracy of your mixture by employing our
exclusive interlocking feature: the concentrations determined from both certification
processes must agree (interlock) with each other within 1%. Both blending and laboratory
processes are traceable to recognized metrology organizations or internally developed
Air Liquide Reference Standards (ALRSs). These standards help you to improve the value
of your end product by facilitating precise instrument calibration accuracy, tighter process
control and credibility.
Single-Certified Standards
Single-certified standards provide the certified concentration from one independent
method—either the blending process or laboratory analysis. Specifications are achieved
by the accuracy and traceability of the blending process or the laboratory analysis.
Air Liquide offers three choices for single-certified standards:
n ACUBLEND™ Master Class™
n Certified Master Class™
n Certified Working Class™
Single-certified standards can be used for primary calibration of instrumentation. They are
also frequently used as validation standards after the instrument is calibrated with a dual-
certified standard such as a Reference Class product.
Custom Standards
A discussion of SCOTT gas and liquid mixture products would not be complete without
highlighting the availability of custom standards—custom mixtures engineered to your
specifications. The manufacturing of custom standards is a tradition, reflecting our ability
to blend mixtures specifically designed to successfully meet your applications. See page
14 for a listing of components available for blending.
InterlockedConcentrations ±1%
Interlocking Concentration Values
These values provide the highest possible
degree of accuracy in a calibration
standard. The concentration value
determined during the blending process
is compared with an independent
concentration value obtained through
laboratory analysis after the blending
has been completed. Interlocking values
occur when both values agree within
±1% of each other.
Interlocked concentration values are
available exclusively from Air Liquide and
represent the utmost level of accuracy
and confidence available in any calibration
standard.
All Reference Class products are provided
with interlocked concentration values.

Unique SCOTT™ TechnologyAir Liquide’s commitment to continuous innovation in specialty gas technology has resulted
in an impressive portfolio of mixing, blending and analysis capabilities. These technical
innovations, coupled with 100 years of experience in the business, allow us to achieve un-
equalled product specifications, regardless of the nature of the components in the mixture.
Certain technologies and product attributes are only available from Air Liquide.
Guaranteed Mixture Stability Begins with ACULIFE™
SCOTT ACULIFE is a suite of proprietary cylinder inerting treatments, utilized to enhance
the stability of reactive gas and liquid mixtures. These chemical vapor deposition processes
eliminate gas-to-cylinder surface interactions to provide guaranteed stability for ppm and
sub-ppm calibration standards, making possible a variety of unique and innovative products.
For example, Air Liquide is the leading supplier of hydrogen sulfide in air mixtures, with
guaranteed stability for safety and industrial hygiene applications. We also have unique
hydrogen chloride gas standards in the low ppm range, made possible by ACULIFE.
SCOTT ACUBLEND™ Produces Zero Blend Tolerance
ACUBLEND can produce a gas mixture having a unique feature called Zero Blend Tolerance.
Zero blend tolerance means no difference between certified and requested concentration.
The process is also capable of preparing a gas mixture precisely within a specified blend
tolerance. ACUBLEND enables Air Liquide to produce identical and homogeneous gas
mixtures in as many separate cylinders as desired. Identical gas mixtures in separate
cylinders have proven valuable by permitting the user to connect such cylinders to a com-
mon manifold, or allowing cylinders having identical concentrations to be used in separate
work areas.
ACUBLEND gas mixtures of identical concentration are ideally suited for 6-pack service.
Typically, customers using this service consume gas from four cylinders (through a common
manifold) that leaves the remaining two cylinders available for emergency and additional
supply until the 6-pack is replaced with another of identical concentration.
SCOTT MICROGRAV™ Enables PPT Concentrations
Air Liquide is the only specialty gas manufacturer to prepare and certify accurate and stable
gas mixtures containing compounds with concentrations approaching parts-per-trillion
(ppt) levels in returnable and nonreturnable cylinders. Our MICROGRAV process is a direct
blending technique that eliminates inaccuracies inherent in serial dilution methods.
Analytical quality control with proven gas chromatographic techniques verifies the accuracy
of MICROGRAV mixtures. ACULIFE inerting cylinder treatment provides one year guaran-
teed stability for mixtures in a nitrogen balance gas. Air Liquide is the primary supplier of
MICROGRAV gas mixtures to NIST and the EPA, as well as to state and other government
agencies. For available MICROGRAV mixtures, contact your Air Liquide representative.
Benefits of Using
SCOTT ACUBLEND Mixtures
n Short production time results in fast
delivery.
n Identical concentrations can be used
with multiple process streams at various
locations to ensure identical calibration.
n Zero Blend Tolerance results in receiving
exactly the concentration you ordered.
n Completely homogeneous mixtures
improve the accuracy and dependability
of ACUBLEND mixtures.
n A virtually unlimited supply of identical

Unique SCOTT Technology
Unique SCOTT™ Technology continued
UNIPHASE™ Liquid Mixtures
Many applications require mixtures containing low vapor pressure and liquid components.
These may be components that are in the liquid phase at normal atmospheric temperatures
and pressures, or they may be components that are in the liquid state at the concentration
and pressure desired in the container. Liquid mixtures can be prepared two ways. In the
first, the blend is made in a conventional cylinder in which the components exist in the
cylinder under their own vapor pressures. In this type of mixture a dip tube, allowing with-
drawal from the bottom of the container, is usually provided. The withdrawal of the liquid
phase minimizes the concentration changes that will occur during emptying of the cylinder
due to fractionation of the more volatile components.
In the second method, the mixture is made completely in the liquid phase using a floating
piston cylinder to preserve mixture integrity. Such mixtures are called UNIPHASE. UNIPHASE
liquid mixtures are highly recommended when mixture components possess significantly
different vapor pressures and solubility characteristics. Air Liquide provides a Certificate
of Accuracy with detailed BTU calculations for all UNIPHASE mixtures. Phase envelopes
are available upon request. Air Liquide representatives will advise you when UNIPHASE
piston cylinders are necessary to ensure a single phase mixture.
SCOTT GRAVSTAT™ Gravimetric Blending
Mixtures that are prepared gravimetrically are produced by weighing the gas components
on a high-load, high-sensitivity analytical balance. Air Liquide uses NIST or VSL weights for
this procedure to assure mixtures are traceable to a reference standard that is certified by a
national or international metrology organization. Our gravimetric process, GRAVSTAT™, takes
into account all statistical parameters including scale weight uncertainty, scale calibration
and the raw material impurities of all pure components in multi-component mixtures. As a
result of GRAVSTAT, Air Liquide can assert the process accuracy by calculating gravimetric
uncertainty and properly representing the true value of component concentration.
Mixture Safety
Air Liquide carefully engineers every mixture to assure that the mixture can be made safely
and reliably. Gas mixtures containing both oxidizing and reducing agents, such as those
containing a fuel plus an oxidizer, can be safely prepared but only if the concentration of
the flammable component lies outside the flammable range. Since a flammable range
varies with temperature and pressure, it is difficult to state a specific rule concerning the
preparation of these mixtures. Air Liquide uses sophisticated engineering software to per-
form the necessary calculations. Generally, a mixture containing a flammable gas and an
oxidizer can be prepared at reduced pressures if the concentration of the flammable com-
ponent is less than 50% of the lower flammable limits.

SCOTT™ Interference-Free™ Multi-Component Protocol Gases
With the advent of acid rain legislation, Air Liquide pioneered the development of Interference-
Free multi-component protocol gases. This innovation set a new industry standard by
allowing utilities to switch to multi-component protocol gases in order to save time and money
in calibration auditing and cylinder handling. Interference-free technology also alleviated the
concern regarding mixtures of sulfur dioxide, nitric oxide and carbon dioxide where high
concentrations of CO2 can interfere with NO analysis on certain traditional analytical instru-
mentation. This interference-free technology is built into every RATA and Compliance
Class™ multi-component product.
RATA Class™ Protocol Gases: Most Accurate Protocol Available
SCOTT RATA Class protocol gases are recommended for all environmental applications
requiring the highest degree of compliance certainty, including:
n Primary calibration
n RATA tests
n Linearity tests
n CGAs and audits
RATA Class protocol mixtures are engineered to achieve ±1% accuracy, which makes RATA
Class protocol gases especially valuable for Relative Accuracy Test Audits. Many utilities
and other industrial facilities are pushing the performance of their continuous emissions
monitoring systems (CEMS) far below the ±10% RATA requirement of the EPA’s Acid
Rain Program to save the $30,000 – $70,000/year cost for RATA testing by achieving the
EPA ±7.5% accuracy limit. The RATA Class protocol is a critical element in achieving these
savings. This class also provides accurate measurements of SO2 and NOx emissions
thereby facilitating emissions trading credits where allowed.
RATA Class mixtures are dual-analyzed. For each reactive component, two separate analy-
ses are performed and analyzed directly against metrology institute standards to determine
the concentrations. Air Liquide’s proprietary analytical technology created the capability
for these two measurements to agree with each other within ±1%, even in two, three or
four-component mixtures. An easy-to-read Certificate of Accuracy is provided with each
RATA Class mixture as illustrated on page 90.
Compliance Class™ Protocol Gases: ±2% Accurate
SCOTT Compliance Class protocol gases meet EPA requirements for less demanding
environmental measurements. Compliance Class mixtures also feature dual-analysis and
NIST standard traceability. A Certificate of Accuracy is provided with each Compliance
Class mixture.
Impact of Interference
A Comparison Between Traditional
and New Advanced Technology

Cost-Effective and Dependable
Calibration
Reference Class mixtures are appropriate
in applications such as hydrocarbon
processing, where high-accuracy calibra-
tion is of prime importance. This product
assures reproducibility of your particular
mixture over time. Every subsequent
Reference Class product you receive in
the future is guaranteed to calibrate within
±1% of your original mixture.
SCOTT Reference Class mixtures are engineered to provide ±1% accuracy. They are gravi-
metrically prepared using GRAVSTAT™, dual-certified, and they are available in a wide
range of components and concentrations. Reference Class mixtures are guaranteed to be
traceable to NIST, VSL or Air Liquide Reference Standards (ALRSs), which in many cases
are the only established reference materials in the world.
The Air Liquide Interlock Advantage
Reference Class mixtures receive two rigorous, independent methods of certification, one
during gravimetric blending using our GRAVSTAT process, and the other using proprietary
laboratory analytical procedures from Air Liquide. Each process yields an accurate concen-
tration for each component. These independent concentrations are then interlocked – they
must agree with each other to within ±1%.
Our exclusive interlocking feature allows for two independent determinations of the true
concentration of each component to be built into every mix. These independent measures
confirm one another, and therefore guarantee that our certification processes are unbiased.
Interlocking concentrations work to your advantage allowing you to perform extremely
precise instrument calibrations that will not drift over time. As a result, you can exert tighter
SPC control limits on processes.
Air Liquide provides a detailed Certificate of Accuracy with every Reference Class mixture as
shown on the next page. The analyzed concentration is reported for each minor component.
In mixtures with a concentration above 2%, the GRAVSTAT-determined concentration is
reported and the analyzed concentration is shown. In addition, the requested concentration
is shown and the Certificate of Accuracy also documents the traceability and shelf life.
Benefits and Features
n Dual-certification, independent blending and laboratory analytical values
guarantee the accuracy of your mixture.
n Air Liquide’s exclusive, interlocked concentration values permit precise calibrations
that will not drift over time, allowing tighter SPC.
n Air Liquide Reference Standards (ALRSs) provide traceability over the widest
range of components and concentrations available in the industry.
n Guaranteed ±1% accuracy minimizes uncertainty in critical primary calibration
applications.
n Produced using GRAVSTAT, a gravimetric gas metering methodology for proven
reliability.
n Assured availability from Air Liquide’s regional manufacturing facilities provides
just-in-time delivery to minimize the need for on-site inventory.

GAS AND LIQUID MIXTURES
Single-Certified Standards
ACUBLEND products have been a specialty gas industry standard for over 30 years. More
calibration gas mixtures have been manufactured by ACUBLEND than any other process.
Many customers have come to depend on the homogeneity, consistency and repeatability
of ACUBLEND mixtures for their ongoing, close tolerance calibration needs.
SCOTT ACUBLEND Master Class mixtures are produced using our patented ACUBLEND
and FLEXBLEND™ gas blending and analysis technologies. These unique processes allow
Air Liquide to blend, mix, compress and analyze gas mixtures in a single operation using
either gas or liquid phase minor components. Because the ACUBLEND and FLEXBLEND
processes are so tightly controlled, the cylinders produced from them are completely
homogeneous from top to bottom within the cylinder, from cylinder-to-cylinder, and even
from batch-to-batch. Each cylinder contains a mix that has a single-certified analytical
concentration, accuracy and traceability when the blending is finished.
Dynamic Blending Using Proprietary Reference Standards
ACUBLEND Master Class mixtures are dynamically blended using high resolution, real-time
analyzers. We use NIST or Air Liquide Reference Standards (ALRSs) for primary calibrations.
Air Liquide employs extensive, proprietary calibration algorithms to control our analyzers
and achieve an analytical accuracy of ±1% or ±2%, depending on the concentration range
you choose.
SCOTT ACUBLEND Master Class mixtures are backed by our state-of-the-art process con-
trols and include those mixtures where our knowledge of real-time sensors and calibration
techniques has demonstrated that an interference-free measurement can be made in real
time and within our analytical accuracy specifications. As with our other product classes,
raw materials are carefully selected and verified to purity specifications prior to use in the
ACUBLEND process.
Air Liquide provides a detailed Certificate of Accuracy with every ACUBLEND Master Class
mixture as shown on page 94. The analyzed concentration is reported for each minor
component. In addition, the requested concentration can be shown.
Benefits and Features
n Short production time results in fast delivery.
n Identical mixture concentrations can be used with multiple process streams at various
locations to ensure identical calibration.
n Zero Blend Tolerance results in receiving exactly the concentration you ordered.
n Completely homogeneous mixtures improve the accuracy and dependability.
n A virtually unlimited supply of identical mixtures—from cylinder-to-cylinder and
batch-to-batch—eliminates the need for recalibration due to variations in mixture
concentrations.
Recommended Applications
n Calibration for multiple users
n Auto emissions test cells
n Multi-facility calibrations
n Long-term or recurring calibrations
n Homogeneous consumable process
materials
n Applications requiring large volumes
of a given mixture
Zero Blend Tolerance
Upon request, ACUBLEND Master Class
mixtures can be manufactured with
a unique attribute we call Zero Blend
Tolerance. Zero Blend Tolerance simply
means “no deviation from ordered
concentration,” in that the concentration
we produce for you is the same as the
concentration you requested.
Zero Blend Tolerance is a very useful
feature for those applications where you
need a calibration standard at an exact,
specified concentration, or where a
new calibration standard that you order
must match up exactly with your existing
ACUBLEND Master Class mix currently in
use. Repeat orders can perfectly duplicate
prior orders and cylinders can be inter-
changed with no harm to your process.

GAS AND LIQUID MIXTURES
Single-Certified Standards
SCOTT Certified Class mixtures offer the largest selection and combination of components,
concentrations, balance gases and cylinder options. You may choose from any compo-
nents listed on pages 14 and 15, or contact Air Liquide to discuss your custom applica-
tions. Components can be blended into a variety of balance gases, such as the traditional
nitrogen, air or helium. The Certified Class mixtures even offer you the option of blending
components into difficult hydrocarbon gas and liquid phases such as methane, ethylene
or liquefied petroleum gas (LPG).
In Certified Class, both reactive and nonreactive components are available in almost any
concentration range, and with one, a few or a large number of components, limited only
by the physical properties and chemical reactivities of the components themselves.
Air Liquide has successfully produced mixtures with more than 100 components to meet
specialized customer needs.
Certified Master Class™ Mixtures
Certified Master Class mixtures are blended using high-accuracy gravimetric, volumetric or
our patented ACUBLEND™ and FLEXBLEND™ techniques, depending on the components,
concentrations and combinations you select. This class of mixtures is single-certified, that
is, the stated (certified) concentration is determined from either the blend process or from
instrumental analysis. For Certified Master Class mixtures, the accuracy of the certified
concentration is typically ±1% or ±2% depending on the concentration range you select.
While some suppliers offer gas mixtures they refer to as being “certified,” Air Liquide’s
Certified Master Class mixtures feature both guaranteed concentration and accuracy for
each component in your mix. As a result, you can be certain that your Certified Class mix-
ture meets Air Liquide specifications.
Certified Master Class products provide you flexibility in component selection. Raw materials
are carefully selected and analyzed to control impurities prior to use, even in cases where
rare, unusual or customer provided materials are used. Further, and prior to manufacture,
Air Liquide conducts extensive engineering for every Certified Class mixture to assure that
each mixture can be prepared safely and that no uncontrolled cross-contamination or
cross-interference will occur.
Air Liquide provides a detailed Certificate of Accuracy with every Certified Master Class
mixture. The certified concentration is reported for each minor component. In addition,
the requested concentration can be shown indicating the blend tolerance specification
ordered, a useful feature for reordering. Every Certified Master Class Certificate of Accuracy
also documents the process traceability and shelf life. A sample certificate is shown on
page 97.

Fuel Gas BTU Analysis
In-plant heating and power generation
processes represent one of the biggest
operating costs faced by refineries, petro-
chemical and chemical plants. Accurate
determination of the BTU content of fuel
gas is an important facet of controlling
energy costs. By using SCOTT Certified
Class mixtures, many oil and chemical
companies have reduced their energy
costs through accurate determination of
the BTU content of their fuel gas streams.
For custody transfer or sales applications,
we recommend using Reference Class
mixtures.
Fired Heater and Furnace
Optimization
SCOTT Certified Class mixtures may be
used to accurately analyze the levels of
oxygen, carbon monoxide and unburned
hydrocarbons contained in the exhaust
gases from fired heaters and cracking
furnaces. With out accurate analysis and
proper control of these components,
a plant’s energy costs would skyrocket.
Certified Class mixtures will help you
reduce your energy costs by providing
you with an accurate analysis so that
you can better control these critical unit
operations.
Certified Working Class™ Mixtures
SCOTT Certified Class mixtures are used in a wide variety of laboratory and online instru-
mentation applications such as primary calibration and validation under statistical process
control (SPC). Your specific requirement will drive the choice of class.
Air Liquide selects the appropriate high-accuracy gravimetric, volumetric or dynamic process
to blend your Certified Working Class mixture, depending on the components and con-
centrations you select. Working Class mixtures are single-certified, and the accuracy of the
certified concentration ranges between ±2% to ±5%, depending on the concentration range
you select.
Certified Working Class products also provide you with tremendous flexibility in component
selection and combination. Air Liquide practices the same careful raw material quality con-
trol and preblend engineering as used in Certified Master products to assure a reliable and
safe mix. An added benefit, depending on your specific needs, is that a Certified Working
Class product may actually be available at a lower concentration or for a more reactive
component than for the corresponding Certified Master Class, because of the wider tol-
erances allowed by the Certified Working Class specifications.
Air Liquide provides a detailed Certificate of Accuracy with every Certified Working Class
mixture. The certified concentration is reported for each minor component. In addition, the
requested concentration can be shown indicating the blend tolerance specification, a useful
feature for reordering. Every Certified Working Class Certificate of Accuracy also documents
the process traceability and shelf life.
Pushing the Technical Envelope
When your specialty gas application has challenging specifications, Certified Class Mixtures
from Air Liquide are an excellent choice. No other specialty gas manufacturer combines
leading-edge mixture specifications with such great flexibility in component selection,
concentration or combination. When no one else can do it, contact Air Liquide, receive
technical support and get your job done right.

Air Liquide, in conjunction with Spectra Sensors and COSA, developed a proprietary technology for the certification of moisture standards.
Green cylinders, as they are known in the industry, are available in the balance gases listed below, as well as helium and others. The values
are interlocked using independent measurements from the gravimetric addition and the analytical results, and must agree within ±5%.
Air Liquide is the world's foremost
authority and supplier of environmental
calibration gas mixtures.
With an extensive portfolio that includes
SCOTT™ RATA and Compliance Class™
products, we offer the industry's most
accurate calibration standards engineered
to help avoid noncompliance fines.

Experts in EPA Protocol Gases
You could be risking noncompliance and the expense of unnecessary RATA tests. Consider
these important facts you should know before you purchase another EPA protocol gas.
n Cost-efficient utilities typically save $30,000–$70,000/year or more in repeat
RATA testing by achieving Acid Rain Program relative accuracies below the EPA’s
7.5% specification.
n Direct traceability to SRMs, PRMs and NTRMs is essential for protocol accuracy.
n Traceability to GMIS standards can degrade accuracy to worse than ±2%.
n G2 analysis leads to uncertainty and questionable protocol accuracy.
n Some multi-component protocol mixtures may cost less – at the expense of accuracy.
n Mathematical corrections, when producing multi-component mixtures, do not provide
the same degree of certainty as FTIR technology.
Trust the Experts in EPA Protocol Gases
Air Liquide is the world’s foremost authority and supplier of environmental calibration gases.
In fact, we developed the original EPA protocol gases guidelines, were actively involved in
subsequent revisions, and currently participate in other important EPA gas calibration
guidance. We offer two classes of EPA protocol products that are instrumental in helping
industries avoid noncompliance fines and downtime caused by inaccurate instrument
calibration.
SCOTT™ RATA Class™ protocol gases are recommended for applications requiring
the highest degree of compliance certainty, including primary calibration, RATA tests,
and quarterly CGAs and audits. RATA Class protocol mixtures are dual-analyzed and
manufactured to achieve ±1% accuracy.
SCOTT Compliance Class™ protocol gases meet EPA requirements for less demanding
environmental measurements. Compliance Class mixtures also feature NIST standard
traceability. They are dual-analyzed and manufactured to achieve ±2%.
For detailed information about the features and benefits of SCOTT EPA protocol gases, see
pages 86 to 89 in the Mixtures section of this catalog.
Partners in Proficiency Testing with Louisiana DEQ
Air Liquide is the only specialty gas supplier authorized by the Louisiana State Department
of Environmental Quality to supply proficiency testing (PT) samples. Those applying for a
license to perform stack or engine emissions testing in Louisiana must first accurately an-
alyze a blind PT sample provided by Air Liquide. The applicant submits their analysis results
to Air Liquide for evaluation. Air Liquide reviews the analysis and determines a pass/fail
result. Once the applicant passes, Air Liquide will generate a Certificate of Analysis for the
original PT sample and issue it to the applicant, and submit the results of the PT evaluation
to the DEQ.
Beyond Accuracy
SCOTT RATA Class EPA Protocol Gases
deliver ±1% accuracy which is critical for
environmental regulatory compliance.
However, according to the EPA, you’re still
likely to fail an environmental audit for
three key reasons.
Air Liquide can protect you against
these three major pitfalls with
SHOP@airliquide™ online inventory
management system.
1. No Certificate of Accuracy on File
Air Liquide gives you dependable, 24/7
online access to a Certificate of Accuracy
for every protocol in your inventory – you’ll
never lose or misplace another certificate.
2. Expired protocol gas in use
Air Liquide sends you an email alerting
you when a cylinder in your inventory
reaches its expiration date – you
won’t run the risk of inadvertently
using a protocol gas that may no longer
be accurate.
3. Cylinder pressure below 150 psi
Air Liquide provides the option of sending
email alerts when the pressure of a
cylinder in use at your facility reaches low
levels – you can promptly change out the
cylinder before a violation occurs.

Special Applications
Low NOx Permitted Units
n Gas turbines
n Coal burning facilities
n Boilers/furnaces
SCOTT™ Low NOx EPA protocol gases from Air Liquide are unique in the environmental
industry. With guaranteed ±1% accuracy in concentrations as low as 0.1 ppm, they provide
the highest reliability and level of confidence for meeting environmental compliance require-
ments. They are invaluable for use by stack testers and utilities, and can be used for
Relative Accuracy Test Audits (RATAs). SCOTT Low NOx EPA Protocol Gases are dual-
analyzed using EPA G1 or G2 methods. Two independent analyses are performed after the
blending process has been completed in order to determine the concentration for each
component. As per EPA requirements, the values obtained from these analyses must agree
to within ±1%. Air Liquide also manufactures Interference-Free™ Low NOx EPA Protocols
with CO or CO2, creating the only dual-component low NOx protocol gas available today.

SCOTT CEM DAILY STANDARDS
161
Air Liquide offers two grades of CEM DAILY STANDARDS. These standards are typically used in applications where the use of EPA protocol
gases is not required. Zero blend tolerance is available with our proprietary ACUBLEND™ technology so multiple cylinders are produced
at the same concentrations. This minimizes the need to recalibrate from cylinder to cylinder. The following table lists available mixtures for
both grades.
CEM 1% DAILY STANDARDS provide ±1% analytical accuracy to help reduce errors in calibration and linearity. Use these standards to
help maximize CEM system performance on a daily basis.
CEM 2% DAILY STANDARDS provide consistent ±2% analytical accuracy for those mixtures for which it is not possible to achieve ±1%
accuracy. This accuracy is comparable to the ±2% minimum accuracy requirement of an EPA protocol gas mixture. Use these standards
to maximize daily CEM performance in applications where ±1% analytical accuracy is either unavailable or unnecessary.

Mercury Verification ProductFossil-fueled power plants may be monitoring their mercury stack emissions in accordance
with EPA 40 CFR Parts 60 & 75. Thermo Fisher Scientific’s popular Model 80i Mercury
Analyzer uses small amounts of 900 ppm chlorine gas (in nitrogen balance gas) for a weekly
integrity test of their analyzer system. Drawing on the principle of gas phase titration, ele-
mental mercury vapor is combined with dilute chlorine gas from a small cylinder to form
mercuric chloride. The mercuric chloride is then injected into the probe filter and through
the entire system to calculate/confirm the conversion efficiency. This process takes place on
the stack at the point of injection. The chlorine gas is available in a disposable cylinder with
a matching regulator per the specifications to the right.

Landfill Gas Applications
Landfill gas (LFG) is composed primarilyof methane and carbon dioxide but alsocontains trace quantities of other Non-methane Organic Compounds (NMOCs).Although these NMOCs represent only a fraction of the total LFG, uncontrolledemissions may exceed the Title V majorsource thresholds for VOCs. Many havebeen designated as Hazardous Air Pollutants (HAPs) under the Clean Air Act,and therefore may be the driving forcefor air regulatory compliance.
Chemical/Rubber Applications
Fugitive emissions from production ofstyrene-butadiene polymers may containlow level aromatics and hydrocarbonsthat have been identified as HAPs. Theaccurate determination of these con-taminants will be critical to the regulatorycompliance of the producer.
