Title: Determination of aromatic hydrocarbons in workplace air by rapid capillary gas chromatography
Abstract: Objective:A rapid capillary column GC method was developed to determinate aromatic hydrocarbons in the air of workplace.Methods:The workplace air was collected by active carbon tube,extracted with carbon disulphide,separated by 20 m×0.18 mm×1 μm DB-VRX capillary column and determinated by GC.Results:The precision was 0.81%~2.4%,the limits of detection 0.017~0.024 μg/ml and the correlation coefficient 0.9998~1.000.The desorbed efficiency exceeded 95% except styrene.The samples were stored at ambient for at least 7 days.Conclusion:The method is sensitive,accurate and rapid.It is applicable to workplace air aromatic hydrocarbons measurement.
