High Volume Air Sampler
|Within Vocab||SeaVoX Device Catalogue|
|Definition||An atmospheric sampler that pumps air through a series of filters and traps to collect samples for off-line analysis of aerosol and gas-phase constituents. Air samples are drawn into a sheltered housing, and through one or more aerosol filters, which collect samples of particulate material. Successive aerosol filters may have smaller pore sizes to collect size fractionated aerosol samples. The air may then be drawn through one or more gas-phase filters or traps, such as reagent-soaked filter papers, reagent-filled impingers, or resin (polymer) traps. Flow meters between the filter set and the pump determine the volume of air sampled.|
