    Active Air Sampling

    How do I take an air sample?

    Active air sampling involves three things:

    One a simple pump to pull air to sample media through which to pull the air and through a pump calibrator to indicate and verify how much air is pulled. To sample air particles such as dust, mists, and fumes, and smoke. Filters in cassettes are the typical sample media, the cassette is prepared and loaded into a convenient holder that secures the cassette the holder can be clipped in the workers breathing zone.

    The sample is then attached using tubing to pump that has a calibrated to the recommended flow rate to the recommended flow rate to sample vapors sorbent tube are the typical sample media the glass sorbent tube is prepared and inserted into a holder a protective cover is installed to prevent the tube from breaking the holder can be clipped in the workers breathing zone the sample media is then attached using connecting tubing to a pump that has been calibrated to the recommended flow rate.

    Personal sampling is performed by placing the pump on the worker and the sample media in their breathing zone to measure individual exposure.
    Area sampling is performed by placing the pump in a specific location to determine concentration level at a specific or fixed point.
    Passive sampling alternative for sampling some gases and vapors because a pump is not required, the worker simply wears a small badge-like sampler that collects airborne chemical by diffusion. Then passive samplers that have been scientifically validated then ensure reliable sampling of target compounds by sending chip samples to a laboratory. The laboratory analyzes the samples compare results to exposure limits established by regulatory authorities or other agencies. In summary, perform air sampling and compliance using a sample pump and sample media. Check the flow rate with a pump calibrator. Use a passive sampler if reliable sampling has been verified for target compound after sampling, send to a laboratory for analysis and then compare results was established exposure limits.
