A thermal desorption unit includes a base plate and a pair of spaced apart plates arranged perpendicularly to the base plate and positioned to hold a magazine of tubes between the spaced apart plates. The unit includes apparatus for selectively extracting, handling, heating, and reinserting a tube from the magazine. The tubes are heated to drive off the contents and flushed to clean the inside of the tubes.

An air sampler includes a magazine having a plurality of sampling tubes, and an inlet and an outlet at a sampling position. A tube advancing mechanism sequentially advances the sampling tubes to and from the sampling position. A tube sealing arrangement is provided at the sampling position. An air pump draws air through the inlet, a sampling tube at the sampling position, and the outlet. A control sequentially operates the magazine, obtaining air samples within the sampling tubes.
