초록 ▼

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.

대표청구항 ▼

Apparatus for the detection of the presence of selected materials in an object by the extraction and analysis of vapor samples therefrom, comprising a sampling chamber adapted to accept the object; means for removing a portion of the vapor contents from the object and blending said removed portion with the surrounding atmosphere in said sampling chamber; means for collecting the molecules of the selected materials from said mixture to create a test sample wherein the concentration of said molecules is substantially above the initial vapor concentration thereof; and means for performing an analysis upon said test sample whereby the presence of said selected material is determined.
