Abstract: A method and system for expelling test sample-volumes from luggage/packages includes, in one form, a set of superposed or otherwise cooperating belt conveyor (16, 24) and a cooperating biohazard detection system (14). Luggage articles (L) or packages to be inspected are moved by the belt conveyor (18) and subject to a momentary compressive force to reduce the internal volume of the luggage article or package sufficient to expel some of the interior air within the luggage article or package. The biohazard detection system (14) samples some of the air expelled from the interior of the luggage article (L) and subjects that air sample to various test of undesired or prohibited materials.

Abstract: A method and system for aspirating sample volumes from luggage/packages for testing includes a series of rollers that convey each luggage article or package through a pressurized flow of air; the rollers are organized to subject each luggage article or package to a series of forces or kinetic movements to effect a momentary volumetric reduction and/or cause displacement of the contents to cause interior air to be expressed or aspirated. A sensor suite tests the aspirated air for the presence of proscribed materials, including those related to explosive, hazardous chemicals, and/or biohazards.
