在HP-5毛细管柱上对碳数9以下的轻质芳烃在恒定流速条件下进行色谱分离,通过实例试验得出气相色谱速率方程,然后计算求得理论最佳线流速,模拟出总体有效线速度,在总体有效线速度下,通过柱温的优化使得容量因子或分配比(见正文)最小,进而提高柱效. On a HP-5 capillary column, the light aromatics with carbon number of 9 or less were chromatographed at a constant flow rate. The gas chromatographic rate equation was obtained through an example experiment, and then the theoretically optimal linear flow rate was calculated to simulate the total effective line The speed, at the total effective linear velocity, is optimized by the column temperature to minimize the capacity factor or distribution ratio (see text) and thus improve the efficiency of the column.
