Application Note 134: Rapid forensic analysis of fire debris using headspace sampling onto sorbent tubes with TD–GC–MS
This Application Note describes the analysis of ignitable liquid residues (ILRs) from fire debris, using static or dynamic headspace sampling onto sorbent tubes, in conjunction with thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS). Key points demonstrated are the ease with which samples can be compared and conditions optimised, the benefits of sample re-collection for repeat analysis, and the very low levels of carryover (even for heavy petroleum distillates).
