| Abstract: | [ Objective] To establish the method for determination of chloroform , ethyl acetate , acetone and benzene in the air by gas chromatography. [Methods] Using capillary column, simultaneous determination of chloroform, ethyl acetate, acetone, benzene was performed with FID detector. [Results] Under the determination conditions, the detection limit of each component ranged from 0.01- 4μg/ml; RSD was 1-5% , the recovery rate was 91. 8-98. 9%. [Conclusion] The method has good separation, high precision, short analysis time and satisfactory results, and meet the operating environment requirements in workplace. |
