本文介绍高效液相色谱(HPLC)与毛细管气相色谱(GC)联机的多维色谱系统。该系统是用微处理机进行自动控制的,可用于烃类化合物的分析。本文采用的 HPLC 是先将石油样品在硅胶上分离成饱和物,不饱和物,芳烃和极性四个组份的化合物,根据这些组分的特点,采用配有火焰离子化检测器的毛细管 GC 进行分析。原文作者在第一报中曾介绍过联机多维色谱技术,利用 HPLC 中的柱转换装置,提供了上述化合物的分布数据。用 HPLC 分离后,再用 GC 鉴定烃类的特征,但这些试验都是脱
This article describes high performance liquid chromatography (HPLC) and capillary gas chromatography (GC) online multidimensional chromatography system. The system is microprocessor-controlled and can be used for hydrocarbon analysis. In this paper, HPLC is the first separation of petroleum samples into four compounds of saturated, unsaturated, aromatic and polar components on silica gel. According to the characteristics of these components, capillary GC with flame ionization detector Analyze. The original author in the first article has introduced online multidimensional chromatography technology, the use of HPLC column conversion device provides the distribution of these compounds data. After separation by HPLC, the characteristics of the hydrocarbons were identified by GC, but these tests were off
