METHODS AND DEVICES FOR IDENTIFYING TERRORISTS/CRIMINAL SUSPECTS BY DETECTING CONTACT OF HUMAN SKIN WITH RUBBER PROTECTIVE GEAR

摘要

The present invention relates to devices and methods for detecting a contaminant on a surface, particularly detecting dithiocarbamates on human skin. The devices and methods are further used to identify a suspect or to conduct forensic analysis of a suspect to determine if they have come into contact with protective gear, and particularly rubber protective gear. The device for collecting a sample (1) from a test surface comprises a substrate, a housing and optionally a cap, wherein the housing supports the substrate and the cap protects the substrate from contamination. The substrate may be coded with an adhesive. The housing may comprise a screw or stamp mechanism.
