ABSTRACT:
An apparatus is provided for identifying trace amounts of substances of interest in an air flow. The apparatus includes an inlet for receiving the air flow and an outlet for exhausting major portions of the air flow. The outlet is offset from the inlet. A porous impactor is disposed in alignment with the inlet and is impacted by particles entrained in the air flow. The porous impactor is heated sufficiently to vaporize particles impinging thereon. A detector communicates with the porous impactor and is operative for identifying substances of interest in the vaporized particles.
