摘要:: 研究了多维气相色谱法测定汽油中的芳烃组分及含量。采用气相色谱系统通过色谱柱 1完成汽油中的脂肪烃和醚类组分与芳烃组分快速分离，芳烃组分进入色谱柱 2 使芳烃组分按沸点次序进行分离；进入 FID 检测器检测，采用内标方法进行定量，一次进样，30 min 内获得按沸点分布的详细芳烃组分的定量信息。该方法对于汽油中大于 175 益高沸点的 C9 及 C10+高沸点芳烃组分含量快速检测提供了准确依据。

This article studies the determination of heavy aromatic hydrocarbon components and their contents in gasoline by
multidimensional gas chromatography. The gas chromatography system is used to quickly separate the fatty hydrocarbons and ether
components from the aromatic components in gasoline through column 1. The aromatic components enter column 2 to separate
them in boiling point order, and then enter the FID detector for detection. The internal standard method is used for quantification.
With one injection, quantitative information of the aromatic components with different carbon numbers flowing out in boiling point
order is obtained within 30 minutes. This method provides accurate basis for rapid detection of high boiling point aromatic
hydrocarbon components above C9 and C10 in gasoline.
