| 摘 要： | 从柱温控制的角度对分析标准推荐的实验条件进行了优化和改进,从而保证了正常操作状态下各组分分析结果的准确度全部符合分析标准的规定;色谱运行时间由原来的40 min减少到20 min,而且达到了丙烯中烃类杂质组分完全分离的色谱效果,实现了一次进样分析。色谱仪的占用由原来的3台减少到1台,降低了分析成本。

| Abstract: | The experiment condition recommended by the analysis standard of a big caliber capillary column for analyzing hydrocarbon impurities was optimized with respect to column temperature control,and the analysis accuracy could meet the standard under normal operation condition.The chromatographic run time was reduced from 40 minutes to 20 minutes.The chromatographic result of complete separation of each component of hydrocarbon impurities in high purity propylene was achieved,and the analysis could be completed in one test.The number of chromatographic instruments was reduced from three to one,and the analysis cost was reduced. |

| Keywords: | hydrocarbon impurities high purity propylene packed column with(C4H9O)3PO4 capillary column with changed character Al2O3 column tempreture control accuracy separation effect |
