The Diffusive Monitor

The Diffusive Monitor is a free publication of the Health and Safety Executive CAR Committee (Committee on Analytical Requirements), Working Group 5. This Working Group is concerned with workplace and environmental applications of diffusive sampling for assessing air quality.

The newsletter was started in May 1988 as a consequence of the Diffusive Sampling Symposium held in Luxembourg the previous year and is published approximately once a year. It contains articles on diffusive monitoring techniques and applications, and is a useful source of information on European and international standardisation in this area and of sampling rate data. Contributions are mostly from members of the Working Group, which has an international membership.
