| Definition | An atmospheric sampler that pumps air through a series of filters to collect samples for off-line analysis of aerosol and gas-phase constituents. Air samples are drawn into a sheltered housing, and through a PTFE filter, which collect samples of particulate material. The air is then drawn through a pair of oxalic acid-impregnated paper filters, which trap gas-phase components. The pump is chosen to produce a flow rate of approximately 50 litres per minute. Inline flow meters between the filter set and the pump determine the volume of air sampled. | |
