摘要
用毛细管气相色谱外标法定量测定甲醇中的杂质组分,通过试验,用FID检测器检测粗甲醇的纯度和杂质含量,在采用安捷伦科技有限公司生产的FFAP毛细管柱的情况下,分离度好、精确度高、分析时间短,简便可行,适用于中间过程分析。
Using the capillary gas chromatography with external standard method to deternfine the impurity components in crude methanol quantitatively. The experiment reveals the purity and impurity content of methanol by FID detector. With the FFAP capillary column produced by Agilent, the method has good resolution and high accuracy in short analysis time. It is simple and feasible, and suitable for the intermediate process analysis.
