NPL has one of the most experienced teams of scientists in gas analysis in the world. We produce an extensive range of gas calibration mixtures through a chain of direct comparisons to our national standards. These are used to underpin highly accurate measurements of ambient air quality, natural gas, industrial emissions, vehicle and aircraft emissions, odour measurement and occupational exposure.

Trace and Electrochemical Analysis
NPL’s research in electrochemistry and trace analysis applies measurement science to an array of trace analysis problems, particularly within environmental matrices. This area encompasses a diverse portfolio of technologies and research in three main areas: Electrochemistry, Trace Analysis, and Surface Enhanced Raman Spectroscopy (SERS).
