Providing ultimate references for highly accurate measurements
NPL is a globally acknowledged authority in metrology, particularly in the field of gas reference materials. As the UK's National Metrology Institute (NMI), we provide traceability for gas-related measurement to internationally recognised standards. We bridge the gap between research and commercial needs, and work in collaboration with NMIs around the world to ensure that measurements are comparable, wherever and whenever they are made.
Our experienced team of scientists works in extensive facilities, providing a unique capability in gas analysis and allowing clients to achieve high sensitivity and precision even at low concentrations. In addition, our strong partnerships with major gas manufacturers like BOC and Air Liquide enable us to offer unrivalled flexibility and quality to our customers, making us the preferred choice for traceable gas calibration solutions globally. We also collaborate extensively with international agencies and research initiatives, including the Aerosol, Clouds and Trace Gases Research Infrastructure (ACTRIS) in Europe, which relies on our standards for long-term atmospheric monitoring.

Reference materials at the pinnacle of traceability
Accurate data in gas analysis is essential for reliable long-term records and modelling, supporting critical decisions in healthcare, food safety and environmental protection. Instrument performance can greatly impact results, with measurement deviations potentially compromising research, product safety and industrial efficiency. Timely, proper calibration using recognised reference materials ensures that measurements meet global compliance and comparability standards.
NPL supplies a distinctive selection of bespoke and off-the-shelf gas calibration mixtures that underpin highly accurate and reliable quantitative measurements in diverse applications, such as monitoring ambient air quality, natural gas, industrial emissions, vehicle and aircraft emissions, odours and occupational exposure. Our gas reference materials represent the highest point of traceability, ensuring unmatched accuracy, stability and reproducibility in gas analysis measurements for clients within academia and industry worldwide.
