Abstract: A detection system assembly is provided. The detection system assembly includes a detector system including a housing having a sample port configured to receive a sample of an unknown substance, a detector assembly in flow communication with the sample port, and a pump in flow communication with the detector assembly. The detection system assembly further includes a dryer cartridge removably coupled to an outer surface of the housing of the detector system. The dryer cartridge is in flow communication with the pump and the detector assembly.

Abstract: A sample collection apparatus for use with a collection trap is provided. The apparatus includes a handle and a sample collection assembly coupled to the handle. The sample collection assembly includes a cradle and a cover. The cradle is coupled to the handle at a first end portion of the cradle. The cradle includes an opening defined therethrough by vertical side walls extending between an upper surface of the cradle and a lower surface of the cradle. The cover includes a projection member and a block. The cover is coupled to a second end portion of the cradle. The projection member includes the block configured to be at least partially inserted through the cradle opening.

Abstract: A method of detecting particles during inspection is provided. The method includes establishing a security checkpoint including a detection system, wherein the detection system includes a chamber defining a passage and includes a plurality of jets. The method also includes passing an individual through the passage, enhancing a convection plume including particles from the individual by blowing air through at least one of the plurality of jets, and absorbing the particles in a preconcentrator including a filter encased in a frame having a high thermal conductivity. Moreover, the method includes evaporating the particles absorbed in the preconcentrator and using a detector to determine whether the particles are from at least one of an explosive material and a narcotic substance.
