Analysis of accelerants in fire debris involves the isolation of residual volatiles from the matrix and the analysis of these volatiles, usually by gas chromatography (GC). The resulting chromatograms are interpreted by comparing to a library of accelerant chromatograms obtained under similar conditions. This review first mentions ASTM's system in classifying fire accelerants into light petrole...
