| Abstract: | On the conditions of helium as carrier gas and using DB-WAX capillary column,by optimizing chromatographic parameters of column temperature,column flow,inlet temperature and detector temperature,rapid analysis of seven kinds of BTEX were conducted.The experimental results showed that BTEX were separated very well within 5.3 minutes.The maximum relative error and the maximum relative standard deviation of the determination average of the standard samples were-1.0% and 2.5%,respectively. |
