中文摘要：

介绍了一种方便快捷、经济成本低，可将芳烃馏分中的萘系和菲系化合物进行快速分离的小型柱色谱法。通过GC—MS分析检测结果表明，此方法可将芳烃中的萘系和菲系化合物得到分离和纯化富集，解决了总芳烃馏分在气相色谱易出现的UCM鼓包和多取代基萘系物和菲系物的共溢出现象。并通过GC—IRMS分析萘系和菲系化合物中单体烃碳同位素值检测。取得了很好的效果。此方法试剂用量少、分析步骤简单快捷，可用于芳烃馏分单体烃碳同位索分析的前处理中。

英文摘要：

An easy and economic method to separate alkylated napthalenes and alkylated phenanthrenes from aromatic hydrocarbons was introduced in this paper. The GC-MS tests showed that this method could provide a complete and enriched separation of alkylated napthalenes and alkylated phenanthrenes from crude oils and sedimentary samples, solving the problem that several methyls were difficult to determine accurately by GC-MS tests because of heavy co-elution and laying the foundation for free carbon isotope tests. As an application, this method can be used for aromatic hydrocarbons of monomer hydrocarbon carbon isotope analysis of pre treatment.
