By using a 20 m narrow bore capillary column, the analytical time has been shortened to 15 min, 5 times faster in comparison with 80 to 90 min by conventional capillary columns, which resulted in higher throughput, higher efficiency and better separation.

• 由于在该方法中采用了细内径毛细管柱,故饱和烃的GC分析周期由原来的8090min缩短至15min,分析速度加快约5倍,大大提高了工作效率和仪器通量,使石油饱和烃得到了很好的分离分析。
