摘要
采用FID检测器，使用DB-5毛细色谱柱，程序升温测定聚四氢呋喃工艺过程中的有机物含量。按照实验所确定的各种分析条件进行分析，使得各组分都得到了很好的分离，分离度均在1．5以上，回收率在98．4％～100．2％之间，分析结果比较准确可靠。
The Organics of the PTMEG producing process was chromatographed on DB -5 capillary column using temperature programmer and flame ionization detector. Under the determined conditionds, the component in the PTMEG production process were separated with good conduction and the known separated components were identified. The method was accurate and repeatable,The recoveries of this method were in the range of 98.4 % - 100.2 %.
