CHEMICAL METROLOGY

Chemical metrology plays a key role in many sectors. The impact of chemical
measurements on the quality of food, medicine and fuel, for example, is
enormous. As such, accurate and traceable measurements of chemical gas and other
compositions are essential.




Introduction


CHEMISTRY

Accurate measurement of gas and other chemical compositions is important in many
different areas, for example environment-related issues and public health. What,
for example, is the “normal” air composition and at what point does a gas become
harmful to our health? To determine this, both background and emission values
must be measured.

To ascertain the quality of natural gas, we determine not only its quantity but
also its calorific value (the amount of energy per unit) by precisely analysing
its composition. Analysis is also essential to ensure a good product for the
development of biofuels.


VSL AND CHEMISTRY

VSL provides various services for the processing and other industries, public
authorities and accredited calibration laboratories as regards traceable
measurements and gas compositions. We are also involved in different research
projects at European level. Our specialists also participate in standardisation
committees. Examples include CEN TC 264 “Air Quality,” ISO TC 158 “Gas
Analysis,” and NEN NC 310 408 “Biomethane,” where work is under way to
standardise energy gases.

CONSULTANCY

We support and advise manufacturers and end users with regard to questions,
enabling them to improve measurement and inspection methods to optimise the
quality of their processes and products.



Customisation


CUSTOM CHEMICAL METROLOGY

The impact of chemical measurements on obtaining high-quality products is
significant, particularly in the process industry and the energy sector.
Examples of such products include food, pharmaceuticals, solvents, polymers and
gaseous or liquid fuels. The products or processes in question can be optimised
by using an efficient, automated measurement strategy and validation method.

Our in-depth knowledge of measurement and the interpretation of measurement data
enables us to provide the following services:

 * Advice on and construction of gas analysis facilities. This ranges from the
   design of measurement set-ups and ensuring traceability to the set-up and
   preparation for accreditation.
 * Development and validation of methods for measuring specific components. This
   results in a report describing these methods and their validation
   methodology, including the determination of measurement uncertainty.
 * Advice for accreditations. A measurement system must meet several
   requirements in order to obtain accreditation. VSL verifies the measurement
   method and measurement data, optimises traceability and calculates the
   uncertainty budget.
 * Support for the optimisation and automation of industrial chemical processes
   in which measurements play a fundamental role in ensuring quality and
   production efficiency.
 * Development of and advice on measurement methods for the enforcement of
   government legislation.

Every situation is unique. Do you need advice or would you like to know what we
can do for you? Don’t hesitate to contact us.




Calibration


CHEMISTRY CALIBRATION SERVICES

The careful verification of chemical compositions requires accurate measurement
data. Analysis equipment and gas monitors should be calibrated regularly to
prevent deviations. VSL calibrates all types of gas analysers. We calibrate
against the highest standards (Primary Standard Materials), resulting in minimum
measurement uncertainties as well as traceability to SI units.

We have a great deal of knowledge of and experience in carrying out measurements
in the field of chemistry. Our calibration certificates are respected and
accepted worldwide.
