Objective To establish a method for determination of N-isopropylaniline in the workplace atmosphere by gas chromatography.Methods Air samples were collected by silica gel tube and desorbed by acetone.Then they were separated through DB-WAX columns and N-isopropylaniline was determined by flame ionization detector.Results The concentration of N-isopropylaniline showed a good linear relationship within the range of 1.40～665.0 μg/ml.The sampling efficiency was 100％.The accuracy was 96％ ～99％ and the precision was 2.1％～7.0％.The minimum detectable concentration was 0.056 mg/m3 (with sampled air volume of 7.5 L).Conclusion The method meets the requirements of analysis and applies to the determination of N-isopropylaniline in the workplace atmosphere.
