Abstract: Determination of perfluoroisobutylene (PFIB) in fluorine chemicals production is reviewed. The difficulties of determination of PFIB are analyzed. Also，the preparation of PFIB standard，chromatography column (packed column and capillary column)，detector are reviewed. PFIB gas chromatography operational condition is given for reference. Finally，requirement for determination of PFIB at different concentrations and the probable trend of PFIB determination are presented.

摘要： 介绍了PFIB分析方法现状；分析了气相色谱法分析PFIB的难点；评述了PFIB气相色谱分析方法中PFIB标样的制备、色谱柱（填充柱和毛细管柱）和检测器；提供了PFIB的气相色谱分析的具体操作参考条件。讨论了PFIB分析方法的研究方向。
