为了排除万能除锈润滑剂对汽油燃烧残留组分准确判定的干扰,采用气相色谱/质谱联用(GC-MS)分析技术,对93~#汽油与万能除锈润滑剂原始样品、燃烧烟尘以及燃烧残留物进行了提取离子谱图分析,并与国标相对比。结果表明,尽管万能除锈润滑剂与汽油燃烧残留组分有很多是相同的,其中燃烧残留物比燃烧烟尘的成分更为相似,但依据国标仍可准确鉴别。
In order to eliminate the interference of universal derusting lubricant on accurate determination of residual components of gasoline combustion, GC-MS was used to analyze the original samples of 93 # gasoline and universal rust lubricant, combustion soot and Burning residues were extracted ion chromatogram analysis, and compared with the national standard. The results show that although the universal rust remover and gasoline combustion residue components are many of the same, of which the combustion residue is more similar to the composition of combustion soot, but according to the national standard can still be accurately identified.
