Abstract
An air sampler includes a stand adapted to support sample enclosures at spaced-apart locations. A multiposition valve is mounted to the stand. The multiposition valve has a plurality of inlet ports and an outlet port selectively fluidly coupled to any of the plurality of inlet ports. A plurality of inlet lines connects the sample enclosures to the inlet ports. A concentrator trap mounted on the stand and coupled to the outlet port concentrates selected constituents from one of the sample enclosures.
