Barrier/Counterbarrier Research. Molecular Sensing.

Abstract

The purpose of this study was to draw a comparison between the sensitivities of present day chemical detectors and sensitivities which are needed for the detection of mines and tunnels. An attempt to determine the levels of concentration of effluents emanating from mines and tunnels is presented. The sensitivities of detectors used with chromatographs and of other direct detectors are given. From these sensitivities it appears that present day chemical detectors are not capable of detecting mines and tunnels. Research areas are suggested (especially the olfactory mechanism) which offer promise for detecting trace amounts of gas with orders of magnitude of more sensitivity and selectivity than present day detectors.
