| 摘 要： | 目的为火场中汽油、煤油和柴油残留物的检测建立一种简便、高灵敏度的ATD／GC／MS检验方法。方法采用Tenax TA吸附管吸附富集检材中的汽油、煤油和柴油成分。然后用美国PE公司的ATD／GC／MS仪器进行全自动的解吸和分析检测。结果检材中汽油、煤油和柴油的检测极限分别达0．05、0.2、0．2pL／mL。结论该方法具解吸和分析检测过程自动化。操作简便快捷，检测灵敏度高。杂质干扰少等特点，可用于实际火场皆汽油、煤油和柴油残留物的检测。

| Abstract: | 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. |
