A process for detection of concealed dynamite was developed and an engineering model designed, built, and demonstrated. The process is based on detection of ethylene glycol dinitrate vapor in air. The essential steps are adsorption of the vapor on a gold surface, desorption from the gold into a short partition column, and passage through an electron-capture detector, whose response is electronically monitored. Nitrobenzene vapor was also detectable, but was distinguishable from ethylene glycol dinitrate vapor. The merits of microwave absorptometry and microwave-heated plasma emission spectrophotometry for detection of dynamite, DNT, and TNT were explored. A method for detection of black powder by characterization of its vapor was not found. (Author)
