Uptake rates for radial diffusive samplers

This application note provides uptake rates for different forms of radial diffusive samplers for workplace and environmental monitoring applications.

Radial diffusive sampling is generally valid for the measurement of airborne vapours of VOCs in a concentration range of approximately 0.3–300 μg/m³ per compound for exposure times of 1–6 hours. However, in some cases, exposure times of up to one week may be used.
