Trace vapor detection technologies are crucial for ensuring reliable and safe detection of explosives and illegal drugs. Researchers have developed a compact testing device called the Trace Vapor Generator for Explosives and Narcotics, which is portable and can be used for non-contact sampling of these vapors. The team reports the TV-Gen can accurately generate trace vapors of low vapor pressure compounds and can produce vapors in complex backgrounds.
