VOC diffusion tubes are suitable for passive or active sampling of vapours for air pollution assessments. A wide variety of sorbents are used to suit the applications required by the user.Suitable for indoor or outdoor air analyses, these tubes are widely used for traffic pollution assessments (including measurement of total petroleum hydrocarbons), monitoring of landfill gas emissions, PAH detection, monitoring of factory outputs, stack emissions testing and personal exposure to hazardous gases. After sampling, the tubes are returned to our UKAS accredited laboratories for analysis with a sample turnaround time of 10 working days.
