Current interests

Dr Andrew Brown leads the delivery of NPL's energy gases work, which develops accurate and traceable standards and methods to underpin measurements of natural gas, refinery gases, LPG and LNG, hydrogen purity and non-conventional gases (e.g. biogas). This work supports a large industrial sector that is rapidly evolving towards a low-carbon future.

Andrew is also responsible for the technical delivery of the UK government's polycyclic aromatic hydrocarbon (PAH) air quality monitoring network, which NPL operates for Defra.

Biography

Andrew is a Principal Research Scientist in NPL's Gas Metrology and Trace Analysis Group, where he has worked since 2000.

During his time at NPL, Andrew has led numerous technical projects and has also formulated the content of a Government funded research programme, acted an as accreditation consultant to the European Space Agency, and played a leading role in a number of international and national standardisation committees. In 2008, Andrew won the CITAC award for the 'most important paper on metrology in chemistry', for his work developing the first traceable measurements of mercury vapour in ambient air.

Andrew is a Chartered Chemist, a member of the Royal Society of Chemistry, and a PRINCE2 qualified project manager.
