Abstract
An apparatus is provided for detecting whether a person has handled explosives, narcotics or other substances of interest. The apparatus includes a metallic sample collection surface on which a person may place a finger. Upon removal of the finger, the metallic sample collection surface is moved to a desorber. The desorber heats the metallic surface sufficiently to vaporize residue transferred from the person. The vaporized residue then is transmitted to a detector for analysis. The detector also may include a fingerprint reading apparatus for reading the fingerprint of the person and comparing the fingerprint to known fingerprint data.
