Analysis of One Kind of Surface Active Agents Using Chromato Probe by Gas Chromatography-Mass Spectrometry

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.
