Objective: To establish a gas chromatography method for detecting isobutyl methacrylate in workplace air. Methods: From July to October 2019, isobutyl methacrylate in workplace air was collected by activated charcoal tube, absorbed using carbon disulfide and analyzed by gas chromatography (FID) with FFAP capillary column. Results: The linear range of isobutyl methacrylate in the method was 0-800 μg/ml, the correlation coefficient was 0.99993. The detection limit was 0.35 μg/ml. The lowest detected concentration was 0.12 mg/m(3). The within-run precision was 2.06%-2.72%, the between-run precision was 3.03%-3.83%. The rates of desorption was 96.7%. The breakthrough volume was 14.46 mg. The average sampling efficience was 100%. The samples could be stored at room temperature for 7 days. Conclusion: The method is simple, highly sensitive and precise. Isobutyl methacrylate in workplace air could be determined accurately.
