GC/MS Data Interpretation for Petroleum Distillate Identification in Contaminated Arson Debris
Extracted ion profiling (“mass chromatography”) and target compound analysis are compared as complementary techniques for the identification of petroleum distillates in fire debris. The positive and negative aspects of both techniques are discussed, including common pitfalls and interpretation suggestions. Neither technique is superior to the other; each has strong qualities where the other has deficiencies. It is recommended that both techniques be applied to GC/MS data for difficult high-back-ground samples.
