Research Advances of Chromatographic Analytical Methods of BTEX

A review on research adavances of chromatographic analytical methods of BTEX in the recent years was presented, especially focusing on the introductions of gas chromatography-internal standard method, and pretreatment methods, such as headspace, solid phase microextraction, liquid-liquid microextraction, et al. In addition, the development direction of analytical methods and the control of BTEX were prospected (49 ref. cited).
