Abstract

A new laboratory test chamber has been developed at INERIS for the determination of diffusive sampler performance. It consists in a loop made of glass, stainless steel and PTFE containing the reference atmosphere where diffusive samplers are exposed. It is possible to accommodate several samplers simultaneously and simulate various environmental conditions such as temperature, wind speed, wind direction, humidity, atmosphere composition, total pressure and exposure duration. Ail working parameters are continuously monitored. It is shown that certain environmental conditions can deeply affect diffusive sampler performances. Thanks to the technical solutions adopted for its design, this chamber allows the determination of diffusive sampler performance in a wide range of experimental conditions in compliance with the new standards for the monitoring of ambient air by diffusive means.
