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."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0550" ; skos:note "accepted"@en ; skos:prefLabel "University of East Anglia Low Volume Air Sampler"@en ; skos:related .
