Title: Simultaneous determination of 7 organic chemicals in workplace air by solvent desorption-capillary gas chromatography
Abstract: Objective:To establish a method for simultaneous determination of benzene series(benzene,tolune,xylene,ethylbenzene,styrene),n-hexane and cyclohexane in air of workplace by solvent desorption-capillary gas chromatography.Methods: The sample was collected with active carbon tube,desorbed by carbon disulfide,and separated with DB-1 capillary column and detected by FID.Results: The 7 organic chemicals could be determined simultaneously,with the relative standard deviations from 3.11% to 4.02%,and the linear ranges of method were from 0.14 to 0.33 μg/ml,the correlation coefficient was more than 0.999.The desorption efficiency were all above 95% except styrene was 80.2%.Conclusion: The method is simple,accurate and suitable for simultaneous determination of the 7 target chemicals in the air of workplace
