摘要
研究了用高效液相色谱法（ＨＰＬＣ）测定润滑油烃族组成的分析方法。以正己烷为流动相，采用色谱柱串联方式，将润滑油分离为饱和烃、单环芳烃、双环芳烃及多环芳烃。通过烃分析检测器检测。该方法速度快、操作简单，各族烃相对标准偏差均小于１０％。
Analysis method of determining PNA in lube oil with high efficiency liquid chromatography is studied. Lube oil is separatedinto saturated hydrocarbon, monocyclic aromatics, dicyclic aromatics and polycyclic aromatics with n-hexane as mobile phase and chromatographic columns connected in series. This method is quick and simple in operation, the relative standard deviations of each group hydrocarbon are all less than 10 %.
