Abstract: The apparatus disclosed herein pertains to the detection of trace explosives or narcotics detection. The apparatus comprises the front-end particle dislodge and sample intake portion of a chemical trace detection system utilizing aerodynamic flow as a transport mechanism whereby compounds indicative of explosives or narcotics contamination are liberated from target surfaces of foot or footwear and then transported by air flow to a sample accumulation feature for chemical analysis. The apparatus is intended for inclusion with additional components, such as an efficient pre-concentrator, a thermal desorption unit, and a chemical analyzer/detector to achieve a complete trace detection system.
