目的 对常用油漆稀料的检验分析方法及分类进行研究,并建立SPME-GC/MS对纵火案件中油漆稀料快速、灵敏、准确的分析方法。方法 采用SPME-GC/MS法对5种不同型号品牌的常见油漆稀料进行分析。结果 确定了样品处理方法和仪器分析最佳条件。实验的5种油漆稀料样本根据组分特征和结构特征的不同可归纳为4类。结论 该研究结果可为纵火案件中油漆稀料残留物提供一种新的检验方法和检验依据。

In this paper, a GC/MS method for analysis of paint thinner was established and paint thinner samples collected in Beijing market were analyzed. The results showed that all paint thinner samples can be classified into four categories according to their chemical composition. This method can be used for determination of paint thinner in fire residues.
