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 , , , composite plastic bag separated by dimethylpolysiloxane capillary column detected by flame ionization detector and Results - () - 3, quantified with external standard method. The linear range of HFO 1366mzz E was 6.82 68 200.00 mg/m with the 3, correlation coefficient of 0.999 9. The detection limit and the lower limit of quantitation were 0.59 and 1.98 mg/m respectively. - - - The recovery rate was within 95.45% 103.05%. The relative standard deviation of within batch precision and between batch - - , 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 - () good sample stability. It can be used for the detection of HFO 1366mzz E in the air of workplace
