| 摘 要： | 原油经过脱沥青处理后 ,采用填充毛细管液相色谱 (PC HPLC)与高温毛细管气相色谱 (HTGC)在线联用技术分析原油中的脂肪烃、芳烃、胶质。样品经过PC HPLC族分离后 ,各族组分峰被依次切割并存放在多位储存接口内 ,再分别无损失地转入GC进行各族组分的定量分析。方法简单、灵活 ,重复性误差 (RSD)≤ 3%。

| Abstract: | The group composition of crude oil was analyzed by on line coupled capillary HPLC HTGC. After removal of asphaltenes, the oil sample was separated by capillary HPLC into aliphatics, aromatics and resins. The interface cut and stored each fraction, and transfered them into GC sequentially. The group contents of oil were determined by FID. The error of reproducibility(RSD) was less than 3%. The method is accurate, time saving, and easy for operation. It is very important for quality control and development of new and better products in crude oil. |
