Gas and Particle Metrology Measurement Services Details of the traceable, high-accuracy gas and airborne particle standards and measurement solutions provided by the National Physical Laboratory About the National Physical Laboratory The National Physical Laboratory (NPL) is the UK’s National Measurement Institute and the birthplace of Alan Turing’s ACE computer, the first universal computer of its kind; packet switching, the basis of the internet; and atomic time, the backbone of GPS and global communications. Our measurement expertise has underpinned prosperity and quality of life in the UK for more than a century. Our role is highly diverse and finds us working on world-leading science and engineering that impacts healthcare, environmental monitoring, advanced manufacturing and the development of next-generation technologies and techniques, with the potential to further transform our lives; from new antibiotics to tackle resistance and more effective cancer treatments, to unhackable quantum communications and superfast 5G.
