In the Remote Explosive Scent Tracing (REST) technology, air from a suspect site is passed through a filter in order to trap the target odor. The filter is then analyzed in a laboratory environment, usually by animals. Although REST is a potentially efficient technology for area reduction, it appears that there has not yet been any strict optimization of the technical procedure. The following work gives a theoretical analysis of the REST concept and first results of a lab study on the performance of various filters for the sampling of gaseous 2,4-DNT.
