A Meticulous Review on Arson Inquest Using Gas Chromatography

Abstract

Arson investigation is hands down the most tedious and the robust form of investigation to go with. It is by far the multifarious and endearing type of investigation as investigating at the arson scene demands high endeavour in order to withstand from all the challenges that stood up at the scene of crime. Stringent norms have been framed by the government that defines it under section 435, 436 and 438 of IPC. In such cases, the chain of custody plays a dynamic and a crucial role as from the procurement of the most fragile samples to transporting it in the most desired form to follow the best sample preparation method before subjecting to GC analysis in order to avail the quality result. Keeping in mind the susceptibility of fire evidences American Society for Testingand Materials International has established standard guidelines for subjecting sample before GC-MS introducing solid phase micro-extraction technique linking to various GC detectors. New minds and innovation has bumped into better and more approachable forms of GC by making hybrids of it such as E-nose i.e. headspace-mass spectrometry, a strategic mass spectrometry based instrument with both qualitative and quantitative applications surpassing the bygone separation process. Revolution in the arson and analytical world is making way for non destructible techniques to serve as a better alternative to any of the GC detectors.
