The collection and determination of ethylene glycol dinitrate, nitroglycerine, and trinitrotulene explosive vapors.

The method presented in this paper demonstrated that minute quantities of explosives such as EGDN, NG, and TNT can be easily detected and determined in relatively large amounts of debris after collecting their vapors on porous polymer beads. The method of collecting explosive vapors is simple, inexpensive, sensitive, and relatively fast compared to microscopic and physical methods of analysis.
