摘要
采用大口径石英毛细管柱分析聚合级丙烯中的烃类杂质。对进样口温度、检测器温度、柱温、气体流量、分流比等参数进行了筛选 ,确定了最佳分析条件。与GB 3392方法相比 ,该法具有操作简单、速度快、准确度高、重复性好、检测灵敏度高等特点。
The hydrocarbon impurities in propylene was determined by using big-caliber quartz capillary co lumn.The parameters such as the temperatures of inlet,analyzer and column,the flow rate of gas ,and the distribution ratio of flow,were selected and the optimum conditions for analysis were determined.As compared with the method of GB 3392,the method had the characteristics of easy operation,fast speed,high accuracy,good repeatability and high sensitivity.
