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.
