Paul Brewer: Dynamic standards and electrochemistry

Dr Paul Brewer is leading research in environmental and reactive gases. His work involves the development of dynamic reference gas standards using techniques such as permeation, diffusion and dilution to provide traceability for environmental monitoring, plastic electronics and the process gas industry. He is also working on novel electrochemical analysis techniques, in particular to reduce the uncertainty of primary pH measurements, and is involved in research into biofuels.


Paul received a First Class Masters degree in Chemistry from the University of Southampton and a PhD in Organic Electronics from Imperial College, London, in 2000 and 2005, respectively. Since then he has worked for NPL. Paul is active on a number of international committees including CCQM and ISO.

Paul has published over 20 peer-reviewed papers.

Paul is a member and Chartered Chemist of the Royal Society of Chemistry.
