Air samples taken on collection media for laboratory analysis remain a highly sensitive and cost-effective means of assessment. However, collection of samples can be difficult using non-automated samplers, particularly over long terms or at remote locations. This paper describes a number of automated air samplers for sorbent-tube and filter use. The samplers are battery-powered, portable and weatherproof. They are suitable for: (1) Very rapid sampling of dual sorbent tubes for survey use. The sampler is very small and lightweight for ease of field use. (2) Sequential sampling of 24 tubes over a period up to 1 month. This technology is suitable for long-term ambient and superfund site monitoring. A meteorological station can be integrated. (3) Simultaneous sampling of 4 separate media at different flows during multiple events over a one month maximum period. This technology is useful for hazard identification and location. One application of interest to the environmental community is the use of a variant of the 24 tube sequential samplers by the United Nations for chemical weapon ban verification. 2 refs.
