GC-MS法检测车用汽油中的甲缩醛、碳酸二甲酯和N-甲基苯胺

Determination of methyl acetal,two methyl carbonate and N-methyl aniline in automobile gasoline by GC-MS

车用汽油检测存在多种方式,GC-MS法是较为常见的一种,该方式具有检测精确率高、操作简单等优势。对GC-MS法检测车用汽油中的甲缩醛、碳酸二甲酯和N-甲基苯胺进行了研究。首先简单介绍了GC-MS法,继而设计了实验方案,最后通过对实验结果分析的方式,提出了文章研究结论。

Currently, the gasoline to detect the presence of a variety of ways, the GC-MS method is a more common, this method has accurate detection rate, simple operation and other advantages. Therefore, the gasoline methylal method was used to detect the GC-MS car, dimethyl carbonate two and N- methyl aniline were studied firstly. GC-MS method is introduced, and the experimental scheme is designed, based on the analysis of the experimental results, this paper puts forward the conclusion of the study.
