Objective To set up a simple and sensitive ATD/GC/MS method for analysis of residues of gasoline, kerosene and diesel oil collected at fire scenes. Method Gasoline, kerosene and diesel oil from fire debris was absorbed and enriched by Tenax TA kit, and then automatically thermal desorbed and analyzed by ATD/GC/MS. Results The minimum detection limit of gasoline, kerosene and diesel oil samples are 0.05, 0.2 and 0.2pl/ml, respectively. Conclusion The method has the advantage of automatic desorbing and analyzing, simple and quick operation, high sensitivity and lower interference of impurities. It can be used for analysis of residues of gasoline, kerosene and diesel oil collected at fire scenes.
