| Abstract: A portal, system and method for screening an object for a target
substance is provided. The portal includes an inflatable bladder
expandable to form a test space for receiving the object and a plurality
of nozzles positioned about the inflatable bladder. The nozzles are in
fluid communication with a fluid source for directing air over the object
whereby samples are removed from the object for examination. A collector
is operatively connected to the inflatable bladder for collecting the
samples removed from the object. A detector is operatively connected to
the collector for examining the removed samples for the presence of the
target substance. At least one preconcentrator may be operatively
connected to the collector for concentrating the samples collected
thereby. |
