吸附色谱/质谱法定性分析柴油烃类组成

Analysis of Hydrocarbon Constituents in Diesel Oil by Adsorption Chromatography/Mass Spectrography

在液－ 固吸附柱中填充１００ ～２００ 目的硅胶，分别选用正戊烷和二氯甲烷为洗脱剂，将柴油分为饱和烃及芳烃两部分。然后再采用色谱／ 质谱（ＧＣ／ ＭＳ） 联用仪分别对饱和烃及芳烃进行分析，得到了关于柴油碳数的烃类组成。

A liquid-solid adsorption column filled with sillica gel of 100～200 mesh was used to separate diesel oil into saturated hydrocarbons and aromatics with n-pentane and dichloromethane as eluents.The saturated hydro carbons and aromatics were analysed with GC/MS to obtain the corresponding carbon numbers.
