| Abstract: | Objective:To establish a method for determination of aromatic hydrocarbons in workplace air by 8-way valve gas injection-gas chromatograpghy.Methods: After thermal desorption and gas injection,the air samples were separated by the capillary column(DB-1) and detected by flame ion detector.Results: The relative standard deviations of retention time and areas repeatablity of the method were less than 0.2% and 3.0% respectively.Conclusion: The method is suitable for the determination of aromatic hydrocarbons in workplace air simultaneously. |
