Gas Chromatography-Mass Spectrometry of Simulated Arson Residue Using Gasoline as an Accelerant

Because gasoline is the most common accelerant used in arson [1], the forensic scientist would like to be able to determine whether or not fire residues contain traces of gasoline. This is a difficult analytical problem since (1) gasoline is a complex mixture of hydrocarbons and special purpose additives and its composition varies unpredictably by brand and refinery runs, and (2) the changes in gasoline composition during the vagaries of a fire are not easy to predict.
