Abstract

In the last decades, the military and Government organizations have an increasing interest in development of field-sensors for homeland security issues. In order to detect explosives (such as DNT, TNT, tetryl, RDX, HMX, TATP, PETN) and some precursors of Improvised Explosive Devices (i.e. potassium sulfate, potassium nitrate, magnesium sulfate, ammonium perchlorate, ammonium nitrate, acetone), we applied laser photoacoustic spectroscopy (LPAS) and a chemometric method (PCA, Principal Component Analysis) to speed up the identification process. The results indicated that the combination of LPAS and PCA is very useful for a rapid identification of these chemicals.
