石油产品和煤液化油烃族组成分析通常采用经典色谱法和高效掖相色谱法。经典色谱法的主要缺点是溶剂消耗大,分析时间长。近年来,国内外色谱工作者用HPLC方法研究了石油及合成油的族组成。J.C.Suatoni等人采用各种方法来分离各族烃,但也只能将试样分为烷烃、烯烃、芳烃三大族,未能将芳烃按环数进一步细分。在检测方面 Petroleum products and liquefied petroleum hydrocarbons The compositional analysis of hydrocarbons often uses classical chromatography and efficient tuck phase chromatography. The main drawback of classical chromatography is solvent consumption, analysis time is long. In recent years, chromatographers at home and abroad have studied the family composition of petroleum and synthetic oils by HPLC method. J.C.Satatoni et al. Used various methods to separate the various hydrocarbon groups, but only divided the sample into three groups of alkanes, alkenes, and aromatics, failing to divide the aromatic hydrocarbons further according to the number of rings.
