POD Sampler
The POD Sampler (POcket Diffusive Sampler) is a radial diffusive sampler for volatile organic compounds (VOCs), compatible with analysis by thermal desorption. Developed in partnership with pioneers in radial sampling at the Joint Research Centre of the European Commission the POD Sampler’s design results in exceptional performance. Compared with axial samplers, radial samplers have a larger diffusive surface area for adsorption and a shorter diffusive pathway.

The POD sampler can be placed almost anywhere and has been used to measure trace levels of VOCs in Antarctica; to define personal exposure of commuters; and estimate emission profiles from oil and gas extraction activities. Additionally, the POD sampler is well suited to fence-line monitoring and can help government agencies, developers and citizens accurately sample pollution levels.
Overview
- 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
The POD Sampler introduces several performance improvements over existing radial samplers:
- The design of the sampler ensures the integrity of data collected by allowing management of potential turbulence effects that can alter the sampling rate
- The smaller amount of sorbent results in a lower level of sorbent artefacts, avoiding interference with trace-level analysis
- The porous diffusive body fits snugly over an adsorbent cartridge, leaving no air gaps. The resulting diffusion path improves reproducibility of results
- Removing and replacing the cover acts as a convenient start/stop mechanism for sampling. The cover also prevents ingress of contaminants during short-term storage
- After sampling, transfer of the cartridge to the shipment vessel is simple, and avoids the need to handle the cartridge directly
Compatible with quantitative sampling of low-level VOCs: Diffusive sampling is used when sampling for known compounds, with quantitation of these being possible by using validated uptake rates. The POD Sampler is compatible with quantitative sampling of low-level VOCs (e.g. BTEX) in the range C4–C9.
Ambient and indoor air monitoring: Large-scale environmental air monitoring studies can benefit greatly from the low cost of using the POD Sampler and the ease of deployment.
Occupational hygiene and personal monitoring: The lightweight design makes the POD Sampler convenient to use, and the rapid uptake rates mean that chemicals harmful to health can be detected rapidly and easily. The removable cover enables start/stop monitoring of specific tasks.
The POD Sampler is available in units of:
- 1 unit for testing and analysis or small-scale sampling
- 10 units to undertake wider testing in your own application
- 100 units for large-scale applications in the field
