Project Description

Ignitable liquids (ILs), such as gasoline and petrol fuel, are common chemicals used in the initiation of arson attacks. Their detection and profiling from debris is, therefore, of strong interest in forensic science and could provide vital evidence to assist in criminal investigations. A range of different techniques are currently available for this purpose. Even if helpful, however, implementation of these techniques is often a compromise between various parameters (including sensitivity, selectivity, simplicity and automation) which may limit their application and throughput in a number of different situations.
This project aims to develop new, high-performant, headspace extraction approaches for the analysis of ILs, in order to provide forensic scientists with better tools to assist law enforcement agencies in the investigation of fire-related incidents. Particular focus will be placed on dynamic in-tube extraction (ITEX) coupled with gas chromatography. Previous works, indeed, have shown that this novel technique may offer enhanced performance (in terms of analytical sensitivity, comprehensiveness and rapidity) for the analysis of volatile organic compounds in a large range of different matrices. Its potential for the forensic detection and profiling of ILs and related residues will therefore be further explored throughout the project, in order to objectively assess the method’s added value compared to currently available approaches and optimise an easy-to-use solution for implementation in operational contexts. Application of the optimised method to different scenarios and for different purposes, such as transfer and persistence studies, will then also be investigated. This will allow new and fundamental knowledge about the nature of ILs to be collected, which will directly be helpful to forensic scientists for the evidential assessment of analytical findings. The expected outcome is an improvement of current protocols for ILs analysis, as well as enhanced understanding of the chemical behaviour of related residues.
