Air consists of certain semi volatile organic compounds such as PCBs and High Volume Air Sampler is used for the collection of these organic compounds. If these samplers are placed in a position wherein there happens to be a lot of air passage which contains PCBs, the risk of the contamination of the foam gasket that is present near the main air flow path in these samplers, sustains. Now of the gasket itself is contaminated with high amounts of PCB, during the working of these samplers, the gasket starts releasing these PCBs back into the air, and when the testing of the air is done, high levels than expected are observed for PCBs.

In order to maintain the efficacy and efficiency of these High Volume Air Samplers, it is essential to keep a record of the history of each of the samplers used while testing. It is always recommended that these gaskets present in the air samplers should be replaced by Teflon tape so as to ensure that no contamination problems have to be faced again and again. Many models have features of flow regulation, measurement and calibration capability.
