响应因子对高效液相色谱法测定柴油族组成的影响

The Effect of Response Factors on Hydrocarbon Group-type Determination of Diesel by High Performance Liquid Chromatography

摘要: 采用高效液相色谱法测定柴油烃族组成，氰基柱作固定相，正庚烷为流动相，辅以反冲技术将样品分离成饱和烃、单环芳烃、双环芳烃和多环芳烃及胶质等组分，用示差折光检测器进行检测，气质联用仪分析得到的样品分析结果作为高效液相色谱法对饱和烃、芳烃和胶质分析进行定量校正的依据，考察了不同的标样测得的响应因子对定量结果的影响。结果发现，对不同组成的油样选用不同类型的标样测得的响应因子进行定量时，结果差别较大。

Abstract: A rapid analytical method for Hydrocarbon Group-type in Diesel with High Performance Liquid Chromatography (HPLC) has been developed. The samples were separated into: saturates, monocyclic aromatic hydrocarbons, dicyclic aromatic hydrocarbons and polycycl
