原油及岩石抽提物的正构烷烃及异戊间二烯烃是研究油源及油气运移的重要分析资料。这些化合物常用的分析方法是先经化学络合处理,使正、异构烷烃分离后,才能进行色谱分析。因而分析流程较长,并需消耗较大量的有机试剂;同时在热处理过程中轻镏份损失严重,造成分析结果失真。无机盐共熔物柱饱和烃色谱是近年来国外发展的一项新的技术方法。此法用无机盐混合物为固定相,不需经化学络合分离,直接将原油或岩石抽提物进行色谱分析,能圆满快速地得到C_(40)前的饱和烃分析结果。我们在试验中采用无机盐共熔物色谱
N-alkanes and isoprenoids from crude oil and rock extract are important analytical data for studying oil source and hydrocarbon migration. The common analytical method for these compounds is chemical complexation to separate the normal and iso-alkanes before they can be chromatographed. So the analysis process is longer, and consume a larger amount of organic reagents; the same time in the heat treatment process, the loss of light, serious, resulting in the analysis of distortion. Inorganic salt eutectic column saturated hydrocarbon chromatography is a new technology developed abroad in recent years. The method uses the inorganic salt mixture as the stationary phase, does not need to be separated by the chemical complexation, directly analyzes the crude oil or the rock extract, and can obtain the saturated hydrocarbon analysis result before C_ (40) satisfactorily and rapidly. We used inorganic salt eutectic chromatography in our experiments
