The chemical detection of ignitable fuel traces in fire debris is a challenge requiring highly sensitive, hyphenated analytical systems. One coupled system suitable for the task is thermal desorption cold trap injection-gas chromatography-mass spectrometry (TCT-GC-MS). In this study, thermal desorption and cryogenic trapping were optimized to eliminate matrix interferences and to enrich target compounds in fire debris. Subsequent GC-MS provided chromatographic profiles of target ionic species required for the unequivocal identification of accelerants.

Abstract
The chemical detection of ignitable fuel traces in fire debris is a challenge requiring highly sensitive, hyphenated analytical systems. One coupled system suitable for the task is thermal desorption cold trap injection-gas chromatography-mass spectrometry (TCT-GC-MS). In this study, thermal desorption and cryogenic trapping were optimized to eliminate matrix interferences and to enrich target compounds in fire debris. Subsequent GC-MS provided chromatographic profiles of target ionic species required for the unequivocal identification of accelerants.File in questo prodotto:
