| 摘 要： | 在采用美国试验与材料学会(ASTM) D6591标准方法测定柴油芳烃含量的过程中,通过光电二极管阵列检测器(PDAD)检测得到的色谱保留时间值及光谱特征吸收曲线,观察柴油中各类芳烃在极性氨基柱上的分离情况;用PDAD检测器考察了根据ASTM D6591确定的反冲洗时间点B对分析结果的影响,结果发现其允许的变化范围为B±0.2 min。在单环芳烃和双环芳烃分界不明显时,用PDAD检测器可以确定其切割点。

| Abstract: | When using ASTM D6591 to determine the content of aromatic hydrocarbons in diesel oil, a photodiode array detector (PDAD) was used to monitor the separation of aromatic hydrocarbons. The influence of back flush time B was studied and it was observed the results of di-aromatic hydrocarbons or poly-aromatic hydrocarbons will give errors when the back flush time is more than B +/- 0.2 min. The PDAD can also be used to determine the best cutting time between mono-aromatic hydrocarbons and di-aromatic hydrocarbons, when the separation was not baseline resolved. |
