The Confirmation of Volatiles by Solid-Phase Microextraction and GC–MS in the Investigation of Two Traffic Fatalities
W.E. Brewer, R.C. Galipo, S.L. Morgan, and K.H. Habben
A simple, sensitive, and reliable method was developed for the confirmation of nonroutine volatiles in the investigation of two traffic fatalities. Solid-phase microextraction (SPME) fibers were used to extract volatile compounds from the headspace of sample vials; components were subsequently analyzed by gas chromatrography–mass spectrometry (GC–MS). In the first case, ethanol and methylene chloride were detected in a urine sample by headspace SPME and GC–MS. The second case involved the analysis of volatile petroleum products from submitted specimens by headspace SPME and GC–MS. In both cases, SPME and GC–MS analyses provided crucial evidence in the investigation of the traffic fatalities.
