中文摘要:

      采用气相色谱质谱电子轰击技术以固体直接进样方法成功地对表面活性剂进行了分离定性.测定了表面活性剂中各个成分的加成环氧乙烷数,定出了各个组分的分子量.

英文摘要:

      A mthod by using chromato probe to analyze one kind of high viscous active agent was proposed. The result is satisfactory. Investigation on the EI fragmentation were reported. Based on a series of main mass fragmentation and the mass intervel between ion fragments, the molecular weight of each component in this type of surface active agent and the number of EO that were additioned was determined.
