DI-SPME method for the analysis of fire accelerants in simulated fire debris samples using GC/MS and GC×GC/Q-TOFMS

Key Points

• The DI-SPME method successfully identifies fire accelerants in complex simulated fire debris samples, enhancing forensic analysis.
• Key evidence shows that using GC/MS and GC×GC/Q-TOFMS detected multiple compounds effectively in controlled tests.
• Assessment using the DI-SPME extraction method facilitates efficient analysis with minimal sample preparation and waste.
• This indicates that further exploration of DI-SPME for fire investigatory techniques could significantly improve accuracy in real-world applications.
