Title: Determination of Benzoles in Ambient Air with Heat Adsorption - Gas Chromatography Method
Abstract: The method of determining benzoles in ambient air with heat adsorption - gas chromatography through adsorption of benzoles with Tenax - TA adsorption tube was introduced.In determining benzoles with thermal adsorption instrument which had two - stage desorption performance,when the sampling volume was 3 L,the detection limit could reach 5×10~(-5) mg/m~3,the accuracy was within the given range of standard sample,and the benzoles sample could remain in Tenax - TA adsorption tube for 12 days.Conclusion showed that the method had advantages of high sensitivity,good reproduction quality,accurate,dependable,and simple for operation,which was suitable for determination of benzoles in ambient air.
