Explosive Trace Detection Swabs
Sample Swabs, also known as Sample Traps or TSA Hand Swabs, are designed to harvest particles from a surfaces for analysis by the ETD instrument. The sample collection process entails the use of specific procedures regarding the item to be sampled with sample collection passes proceeding in a logical fashion across the item to be swabbed to insure complete sample gathering. Explosive Trace Detection swabs for the Itemiser are made of high quality teflon coated fiberglass. This material is designed for use in the ETD device which requires high temperatures to burn off trace elements for identification by the system. Trace detection is based upon the chemical analysis of explosive residues resulting from bomb building or concealment or any encounter with the components of explosives. Similarly, narcotic trace detection is predicated upon the chemical analysis of subject encounters with narcotic components.
