[Objective]To establish solvent desorption gas chromatographic method for determination of air isoflurane in workplace.[Methods]This method was based on "Standardization of methods for determination of toxic substances in workplace air"[Results]This method presented linear relation within 1-7 480 μg/ml.The sample could be stored in the active carbon tube for at least 7 days.Precision(RSD): 0.5%-1.3%.Detection limit: 1.0 μg/ml.Desorption efficiencies were 97.0%-103.8%.Absorption efficiencies were 94.9%-100%.The Breakthrough volume was 100 mg of active carbon for 3.7mg of enflurane.Sevoflurane,isoflurane,ethanol existed in the air were not interferences for determination.[Conclusion]This method meets the requirement of "Standardization of methods for determination of toxic substances in workplace air".It is feasible for determination of enflurane in workplace air.
