Title: Determination of Acrylonitrile in the Work Place Air with Thermal Desorption/Gas Phase Chromatography Method
Abstract: Acrylonitrile in air was adsorbed by Tenax - TA thermal adsorption tubes, and thermal desorption/gas chromatography for the determination of acrylonitrile in the air of work place was established. The detection limit of this method was 4×10~(-5)μg/mL,and average desorption efficiencies were 96. 1%~102.5%. The relative standard deviation of different concentration was 2. 2%~3. 4%. The method is featured by high sensitiveness, good reproducibility, simple operation and long preserving time, which is suitable for determination of acrylonitrile in work place air.
