AFPS - Animal feed
The Animal Feeds Proficiency Scheme (AFPS)
is specifically designed to meet the needs of
laboratories performing chemical or microbiological
analysis of animal feedstuffs.

Animal feed quality is highly regulated since

the majority of animals, or their products, will
be converted into food for human consumption.

EC Regulation 767/2009 stipulates the

requirements for the marketing and use of animal Test material Analytes
feeds, and (with reference to related regulations) Animal feed Chemical

QDCS - Dairy chemistry
The Quality in Dairy Chemistry Scheme (QDCS)
is one of the most comprehensive proficiency
testing scheme available to laboratories performing
compositional and safety analysis in the dairy
sector. EU Regulation 853/2004 introduces
specific hygiene rules applying to raw milk
and dairy products, including control of residual
antibiotics.

When cattle ingest aflatoxins and other

contaminants in feed, toxic metabolites can be
formed and may potentially infect milk, cheese

“How often do I need to participate?”

“The frequency that a laboratory needs to participate in proficiency
testing depends on a wide range of factors specific to each
individual laboratory. Therefore every individual laboratory may
have a different need, which is why our schemes provide flexible
participation, although some do have a minimum participation
level. Third parties, such as regulatory bodies, may recommend
minimum levels of participation. To gain the benefit from trend
analysis, participation in a minimum of four rounds over a scheme
year is normally recommended.”

AIR PT - Workplace air,
ambient air, indoor / chamber
air and stack emissions
The AIR Proficiency Testing scheme is a
collaboration between LGC and the UK Health
and Safety Laboratory (HSL). The AIR PT scheme
is run by LGC and is supported by the technical
expertise at HSL. The scheme combines HSL’s
WASP and LGC’s STACKS schemes, providing an
integrated scheme that is specifically designed for
all laboratories undertaking analysis of samples
derived from various fields of air monitoring.

A common approach to monitor air quality is to

collect gaseous and particulate pollutants on to
suitable sampling media and submit these to the
laboratory for analysis. The aim of the AIR PT
scheme is to support the quality of analytical data
generated by laboratories performing chemical
analysis of the samples taken.

DAPS - Alcoholic drinks
As well as distilled beverages, DAPS covers
analysis of a wide range of alcoholic beverages
and intermediate process samples.

There are five different groups available, with

a comprehensive range of test parameters.

One of the key tests performed within DAPS

is the measurement of alcoholic strength. Duty is
normally paid on the basis of the alcohol in the
beverage, and so it is a key performance indicator
for the product and tax authorities. By monitoring
laboratory performance in this key area,
laboratories can help ensure that overpayment
is not made thus saving money. Underpayment, Test material Analytes

MAPS - Malt analytes
The MAPS scheme covers test materials from
the full range of malted barley and barley used
for brewing and distilling. These test materials
are analysed for a wide range of analytes, using
European Brewing Convention (EBC) and Institute
of Brewing and Distilling (IBD) methods, as well as
a number of other physical and chemical methods.
All test materials are sourced from commercially

DAH - Drugs of abuse in hair
The DAH scheme is suitable for all laboratories
involved in the analysis of hair for drugs of abuse
and provides an independent assessment of
measurement quality.

Drugs and their metabolites become incorporated

in hair when ingested. Therefore, analysis for
these drug residues can provide a useful and
accurate assessment of an individual’s intake of
drugs over a period of time. The detection time
of drugs in hair is significantly greater than other
samples i.e. blood, urine and saliva.

Advantages of analysing hair samples for the

presence of drugs include a large window of
detection, the assessment of the regularity
of drug use and sample stability.

Drug testing is extremely accurate and reliable
when all aspects of the testing process are
carried out correctly. However, if poor procedures
and inadequate testing methods are utilised, the
information obtained may be very misleading
and inaccurate. In order to minimise this risk,
clinical laboratories should perform routine quality
control tests and participate in suitable PT / EQA
schemes.

blood, serum and urine. In general, analyses are
commonly undertaken for a range of prescription
and non-prescription drugs, illegal drugs and
alcohol. The aim of the analyses is to establish
the identity of any substances present and at
what quantity, and to then determine what effect
the substance(s) identified may have had on the
individual. The analytical findings would then be
subject to interpretation by a suitably qualified
individual.

COSMETICS - Cosmetics
and toiletries
The use of cosmetics has been commonplace for
thousands of years, and the potential for harm to
the wearer has been present ever since the use of
toxic chemicals such as lead sulfite (galena) as an
eye make-up by the ancient Egyptians.

Today it is important that contaminated

cosmetics do not enter the supply chain, whether
the contamination is due to excessive levels of
heavy metals, or microbial contamination which can
produce enzymes which can damage the epidermis
causing irritation and potentially infection if applied
to already broken skin.

The COSMETICS scheme covers chemistry and

microbiology test parameters. A lipstick, lip gloss
and powdered cosmetic formulation are available
for analysis of lead and other metals. In addition Test material Analytes

The release of nickel from certain products, most

commonly earrings and other jewellery for body
piercings is the most widespread cause of allergic
contact dermatitis - an itchy rash that appears
when skin touches a usually harmless substance -
affecting people of all ages. Many ordinary items
such as buttons, coins, spectacle frames, watch
straps, zips etc. may also contain nickel and as
such is hard for sufferers to avoid.

The method for the determination of nickel release

from such products is defined in European
standard EN 1811 (2011). The article to be tested
is suspended in an artificial sweat solution for
a period of a week, after which time the
concentration of dissolved nickel in the solution is
determined by ICP-MS or a similarly accurate and
precise technique.

The full range and availability of test materials

in NiMS is determined on an annual basis and
further details can be found in the NiMS application

“What could be the cause of my poor performance?”

“A single poor result is not indicative of overall laboratory
performance but neither is a single good result. Ideally, PT results
should be monitored over time to detect potential bias or repeated
unsatisfactory results. There are numerous potential causes of
poor performance in a PT scheme which may include analytical
and non-analytical errors.”

FIRMS - Forensic isotope ratio
mass spectrometry
Isotope Ratio Mass Spectrometry (IRMS) is a
specialised technique used to precisely measure
small differences in the abundances of isotopes
such as 2H/1H, 13C/12C, 15N/14N and 18O/16O.
Subtle variations to the ‘natural’ abundance of
these isotopes may be introduced during
biological, chemical and physical processes

As a result, isotopic variations are found in diverse

materials and IRMS therefore has a wide range of
applications, in subject areas such as Archaeology,
Geosciences, Biological sciences and Forensic
sciences.
Test material Analytes

Over recent years there has been a surge in IRMS Range of products Variations in isotope ratios.

application most notably in forensic science where
it may be possible to distinguish samples which Note: Test materials and analytes may be added or removed,
otherwise share identical chemical compositions. please see current application form.
FIRMS is currently not included in our scope of accreditation.
A laboratory that has little experience with IRMS
may obtain results that appear accurate but do not
reflect the samples that were analysed.

The Forensic Isotope Ratio Mass Spectrometry

(FIRMS) Network was founded to develop the
scope of stable isotope techniques in forensic
applications. The purpose of the scheme is to
raise awareness of the relevance and importance
of IRMS in forensic science, crime detection and
reduction.

The FIRMS scheme is run by LGC Standards

and is supported by the FIRMS Network which
provides input for the choice of test materials.

The full range and availability of test materials

in FIRMS is determined on an annual basis
and further details can be found in the FIRMS
application form and scheme description.

OIL PT - Oils and fuels
Petroleum products, such as oils and fuels, are
tested throughout their life span, from the time the
oil is taken from the ground to beyond the petroleum
recyclers. The concentration of contaminants and
trace elements is vital in ensuring the quality of oil
and petroleum products. Regulations related to
cleanliness standards in engines; contamination
particles and water in diesel fuel; instability of ultra
low sulfur fuels; and many more, mean it is essential
that laboratories performing these measurements
are capable of producing accurate data.

Quality control materials

Post-report PT test materials available

At the end of PT rounds, material is available for up to 3 months to
the participants in order to investigate any issues with the analytical
process. This is often required by accreditation bodies where there
is no obvious non-analytical error (such as a transcription error)
that could explain the occurrence of a poor score in a PT round.

Value quality control materials

For many of our schemes there is ample stock available after the
report has been issued, and these are ideal for use as quality
control materials within the day-to-day laboratory programme. For
many schemes, the samples are commercially produced materials
with long shelf-lives, making them the perfect solution for many of
your QC requirements.

Proven quality
The assigned value for the PT test materials is supported by the
analysis of many laboratories (in some cases hundreds) and
statistical data processing, to ensure the reported values are reliable*.

Benefits of PT test materials for quality control

• Proven values, fully documented in the PT report
• Excellent value for money
• Ideal for method validation
• May be used to help establish measurement uncertainty
• Perfect for process control between PT rounds
• Excellent training tool for new staff
• Saves time preparing in-house controls
• Helps validate internally prepared materials
• Underpins your internal quality procedures
