Abstract

EVD detection relies on the deposition of explosives traces on the surface of the investigated object. The explosive traces are usually deposited during the preparation process, i.e. packing of the explosive device into the container. If the packaging procedure dates back several weeks, the explosives traces must be stable during this time to be detectable. This necessary stability is given for the high explosives TNT, PETN and RDX. Problems arise with substances, that have high vapor pressures like EGDN, NG and DNT.
