Abstract
A portal vapor detection system for sampling air proximal to the bodies of individuals in which air sampling tubes positioned within movable panels convey a gas flow into an analyzing system. Low vapor pressure materials such as plastic explosives or illicit drugs carried by individuals can be detected thereby enabling the prevention of their transport into aircraft or secured areas.
