Analysis of Explosives in Soil Using Solid Phase Microextraction and Gas Chromatography

摘要

Current methods for the analysis of explosives in soils utilize time consuming sample preparation workups and extractions.The method detection limits for EPA Method 8330 for most analytes is substantially higher than the typical explosive concentrations encountered in soils near unexploded ordnance items,landmines,or other hidden explosive devices.It is desirable to develop new analytical techniques to analyze soil with low concentrations of explosives to support the development of explosive sensors.This report describes efforts to adapt headspace solid phase extraction and gas chromatography/mass spectrometry to provide a con-venient and sensitive analysis method for explosives in soil.
