[Objective] To establish Thermal desorption gas chromatographic method for 1, 3-butadiene in work place air. [Methods]The samples col ected by active carbon were analyzed after thermal desorption at 180℃. [Results] The method showed a good linearity within the concentration range of 0-0.1025 μg/ml (r>0.999). The detection limit based on a signal to noise ratio of 3:1 was 3.39×10-4 μg/ml. The relative standard deviation of peak areas for 1, 3-butadiene standard was 1.43%. The recoveries of the method ranged from 90.86% to 104.90%. Other volatile organic solvents such as methane, butylenes, propylene, n-pentane and n-hexane are not interferential substances. [Conclusion]This method meets the requirements of “Standardization of methods for determination of toxic substances in work place air”. It is feasible for determination of 1, 3-butadiene in work place air.
