摘　　要：介绍了气相色谱/质谱联用法(GC/MS)测定四氟乙烯中双戊烯的方法。GC/MS采用选择离子监测模式(SIM),具有较高的灵敏度和选择性。四氟乙烯中双戊烯的含量通过外标法计算。该方法操作简单便捷,可有效监控四氟乙烯中双戊烯的含量。The method with gas chromatography / mass spectrometry（ GC / MS） was used to determine the content of dipentene in tetrafluoroethylene sample. The mass spectrometer was operated in selected ion monitoring（ SIM） mode. By using this mode,high sensitivity and selectivity were achieved. The content of dipentene in tetrafluoroethylene was calculated by external standard method. The approach was simple to operate,so it can detect the content of dipentene in tetrafluoroethylene sample effectively.
