The Analytical Scientist / Product Profiles / 2022 / Pocket Diffusive (POD) sampler for passive sampling

Pocket Diffusive (POD) sampler for passive sampling

Pocket Diffusive (POD) sampler for passive sampling

The POD sampler is a radial diffusive sampler for volatile organic compounds, compatible with analysis by thermal desorption.

Compared with conventional (axial) samplers, radial samplers have a larger diffusive surface area for adsorption and a shorter diffusive pathway. This results in faster uptake rates, enabling shorter sampling times or increased sensitivity.

  • Robust, easy to use, and suitable for a wide range of common volatile organic air pollutants (C4–C9)
  • Ideal for short-term diffusive sampling of low atmospheric concentrations
  • Reduced effect of environmental variables on sampling rates compared to other radial samplers
  • Can be re-conditioned and cleaned for use multiple times

Compatible with all commercial TD systems.
