A particle impact device for a hand-held trace particle detection system includes an intake manifold that includes a first conduit defining an intake port. The intake port defines a first transport area. The intake manifold also includes a second conduit coupled to the first conduit. The second conduit defines a discharge port that defines a second transport area. The first transport area is greater than the second transport area. The particle impact device also includes a combined deposition and deflection apparatus positioned downstream of the discharge port. The combined deposition and deflection apparatus defines a deposition and deflection surface positioned a predetermined distance from the discharge port. The deposition and deflection surface is configured to deflect a fluid stream and collect at least a portion of particles entrained in the fluid stream.

Hand-held trace particle sampling system and method of operating the same

A sampling system that contains filter components for collecting and concentrating vapor and particles in high-volume flows. The sample is then vaporized and delivered to a detector at a low-volume flow. The invention also has a sampling probe that contains an air-jet to help dislodge particles from surfaces and a heating lamp to help vaporize compounds on surfaces or objects. The sampling system is especially useful for screening for explosives and other illicit chemicals and toxins on people, baggage, cargo, and other objects.

A detector system with a portal including a plurality of output ports that direct a plurality of output airstreams in an essentially horizontal direction, and a plurality of intake ports that pull in air. The system also includes at least one concentrator coupled to at least one of the intake ports, and a detector coupled to the concentrator. The horizontally oriented output airstreams and multiple intake ports provide a system that can rapidly screen multiple people for explosives and other substances.

Method of simultaneously screening a plurality of people

A sampling device that contains a heated porous inlet and a transfer line. The device provides sample compounds present as vapor, liquid, or solid, in air, or on surfaces such as soil. The sample device can collect and deliver the sample to an analyzer in real time and can operate while in motion such as on a moving vehicle. The sampling device is especially useful to screen toxic and hazardous compounds that might be contaminating an inhabited area.
