石油中的芳烃组分不仅含有苯、萘、菲、蒽、芘、苯并蒽、(艹屈)等物质,还含有短侧链的烷基萘、烷基菲系列化合物,也有少量的含硫、含氧芳烃化合物。W·Glger及W·W·Yongblood等论述了古代沉积和化石燃料中含有的上千种芳烃化合物。对这样复杂的混合物,采用高效毛细管柱——弹性石英毛细柱或玻璃毛细柱,选择适当的极性固定液,如:SE-54,SE-52,OV-101,SE-30等,配合色～质谱定性,有可能对石油中主要含量的芳烃进行定性、定量分析。本文讨论了使用OV-101玻璃毛细管柱分析芳烃的色谱条件,典型的芳烃样品经过色质联用,配合芳烃标样及文献保留值等方法定性,约测出40个芳化物。
The aromatic components in petroleum not only contain benzene, naphthalene, phenanthrene, anthracene, pyrene, benzanthracene, naphthalene and other short-chain alkyl naphthalene, alkyl phenanthrene series compounds, but also a small amount of sulfur , Aromatic oxygen containing compounds. W · Glger and W · W · Yongblood et al. Discussed thousands of aromatic compounds contained in ancient sediments and fossil fuels. For such a complex mixture, the use of high-performance capillary column - flexible quartz capillary column or glass capillary column, select the appropriate polar fixative, such as: SE-54, SE-52, OV-101, SE-30, ~ Mass spectrometry qualitative, it is possible to qualitative and quantitative analysis of the main content of aromatics in petroleum. This article discusses the chromatographic conditions for the analysis of aromatics using an OV-101 glass capillary column. The typical aromatics samples are characterized by mass spectrometry, aromatics standards, and literature retention. About 40 aromatics were detected.
