Abstract:
Objective - ，，，，，- - -
To establish a gas chromatographic method for the determination of trans 1 1 1 4 4 4 hexafluoro 2
［ - （）］ Methods - （）
butene HFO 1366mzz E in workplace air. HFO 1366mzz E in air was directly collected with aluminum foil

precision were 2.26% 5.07% and 4.09% 6.82% respectively. The samples can be stored at room temperature for at least seven
Conclusion ， ，
days. This method is simple to use with a wide linear range low detection limit high accuracy and precision and
