| 摘 要： | 采用填充毛细管液相色谱（ＰＣ－ＨＰＬＣ）与毛细管气相色谱（ＣＧＣ）在线联用技术分析油品中的芳烃。ＰＣ－ＨＰＬＣ将油品分成烷烃、芳烃和胶质，其中芳烃按环数和骨架结构分为单环芳烃、双环萘类、双环芴类、三环芳烃、四环芘及荧蒽（Ｃ１６）类和四环苯并蒽（Ｃ１８）类等。ＰＣ－ＨＰＬＣ进样后，各族组份峰被依次存放在多位储存接口内，然后分别转入ＧＣ，分析各族组份的含量及碳数分布。该方法准确，重复性好。

| Abstract: | The aromatics of oil samples were analyzed by an on-line coupling system of packed capillary high performance liquid chromatography(PC-HPLC)and capillary gas chromatography(CGC).PC-HPLC separates the sample into aliphatics,aromatics and resin.The aromatics elute according to their ring numbers and frame structures:one-ring,naphthalene class,fluorene class,three-ring type,pyrene and fluoranthene(C16)type,benzoanthracene(C18)type etc.Each fraction is stored in turn in a multi-loop interface from a single PC-HPLC injection,and then transferred into GC for detailed analysis.The content and the carbon number distribution of each chemical class are obtained.The RSD is less than 5%.Practical examples are given to demonstrate the applicability of the method. |
