Abstract
An apparatus and method for the detection and identification of the presence of chosen molecules, typically toxic or contraband located within sealed luggage and the like, comprises subjecting the sealed luggage to a process whereby a portion of the enclosed atmosphere within the luggage is extracted and combined with the surrounding atmosphere in a closed chamber. The extracted, combined sample is passed to a collector, typically a molecule adsorber, which concentrates the chosen molecules by collection on a collecting surface. After the end of a collection period, the adsorbed molecules are released from the surface and passed to an identifier, such as an ion mobility spectrometer. By use of appropriate collection and valving elements, analysis can be accomplished quickly and accurately for a large number of luggage items or the like subject to examination.
