Trace Explosive Deposition and Detection Verification System

Researchers at the U.S. Department of Homeland Security Transportation Security Laboratory have developed a trace explosive detection verification system leveraging methods to produce standardized solutions of authentic explosive compounds and devices to dispense residues of these compounds onto surfaces at known concentrations. The combined technology leverages specialized solvent systems that dissipate instantaneously upon being dispensed to prevent solvent-substrate interactions and enable more-versatile just-in-time preparations of dry explosive samples for testing. This system can be used to verify that explosive detection equipment is operating properly and to detect specific explosives that it is rated to detect. The DHS technology avoids time and labor associated with traditional dry transfer techniques and results in more-accurate test samples.
