Abstract

A comparison of the relative efficiencies of several established techniques for extracting some common explosives from swabs has been made. Two methods were found to be of a reproducibly high efficiency while a third was much more variable. In an endeavor to reduce the amount of solvent required for extraction, and hence the problems resulting from concentrating the extracts, a new microfilter centrifuge extraction technique was also investigated.
