Historically, arson analysis has consisted of long GC/MS run times followed by the review of the mass chromatographic data. The application of GC/TOF-MS using fast GC techniques can greatly reduce the data acquisition period and when coupled with an automated processing method ultimately reduce the total analysis time.

Currently the analysis of arson samples is laborious and time consuming. This fact is due to both the actual data acquisition and the subsequent manual data analysis. We have shown that through the use of TEMPUS GC/ TOF-MS analysis and automated pattern matching software (Xaminer?) that arson cases can be rapidly and accurately analyzed. Actual time of analysis is reduced by the fact that the high-speed acquisition rate of the TOF enables us to employ fast GC techniques without loss of resolution or sensitivity. The application of automated chromatogram pattern matching software resulted in accurate and rapid identification of actual arson samples and further reduced time spent per sample. This reduction of both run-time and data processing/review time increases sample throughput and productivity. Finally, a repetitive and subjective burden is lifted from the analyst while the analyst?s confidence is increased in the ultimate identification of the accelerant.
