Gas reference materials
Gas Detection / Calibration
Information
We supply 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 and occupational exposure.
As the UK's National Metrology Institute (NMI), NPL provides traceability for gas-related measurement to internationally-recognized standards. We work in collaboration with NMIs around the world to ensure that these measurements are comparable, wherever and whenever they are made.
NPL has signed a Memorandum of Cooperation with the Chemical Sciences Division at NIST. For a selection of components, NPL can offer gas reference materials and calibration services to organisations that require NIST traceability.
