摘　　要：主要介绍利用沃特世公司新型Xevo G2 XS QTOF飞行时间质谱测定丙烯腈中低聚物成分的方法研究。通过考察柱超高效液相色谱分离参数及质谱参数,确定了最佳的分析条件。对丙烯腈样品的浓缩产物进行分析,确定了丙烯腈中存在至少3个系列的低聚物成分。利用QTOF分析数据进一步推测了各种低聚物分子的端基结构。The method to detect the oligomer in acrylontrile with Waters new type XEVO G2XS QTOF time of flight mass spectrometry was developed. The optimal analysis condition was determined by separation and mass spectrometry parameters of the super efficient liquid chromatography in the examination column. At least three series of oligomer existed in the acrylonitrile by analyzing concentration product of the acrylonitrile sample. End groups structures in the oligomers were further inferred by the QTOF data.
