| 摘 要： | 利用甲苯、间二甲苯，邻二甲苯化合物的物理性质差异，以HP-1毛细管柱上的分离过程为探讨对象，对上述化合物的分离行为进行比较。实验表明：通过调节柱温和载气流量可获得较好的分离图谱。并可以用峰分离度指标来衡量。

| Abstract: | Employing the difference of physical property of toluene, m - xylene, o - xylene, taking HP - 1 separation process on capillary column as investigation aim , the article made a comparison between the separation behaviour of the above compounds. The experiment indicated that the better separation diagram may be obtained and measured with target of peak resolution through adjusting column temperature and carrier gas flow rate. |
