Determination of Combustion-Improvers in fire debris

Abstract

Abstract: A simple method for the determination of Combustionimprovers, such as gasoline, kerosene and diesel oil, has been developedby GC/MS, along with extracting and heating devices designed by theauthor. It was found that extracting temperature and moment in SPMEinfluenced the sensitivity of the analysis. In the study, the optimal analyzingconditions were established, and under the condition, the detection limitsfor gasoline, kerosene and diesel oil were 0.65pl/ml, 1.63pl/ml and 1.63pl/ml respectively.

Key words: gasoline, kerosene, diesel oil, SPME, GC/MS

摘要： 运用GC/MS并利用自制的萃取、加热装置,研究在纵火现场助燃剂—汽油、煤油、柴油检测中固相微萃取的萃取温度和萃取时间对检测灵敏度的影响,确定了适于实际检案中采用的萃取时间和萃取温度。此法测定汽油、煤油、柴油的检出限分别为0.65 pl/ml、1.63 pl/ml和1.63 pl/ml。
