Micro-separation in Miniaturized Total Analysis System Xu Yi1,2, Zhang Xiaofeng1, Hai Xianlai1, Lan Yuwei1 (1Chemistry and Chemical Engineering College, Chongqing Univeristy) (2 Photo-electric Tech.& System Key Lab of Chinese Educational Committee, Chongqing 400044) Abstract The importance and conception of micro-separation for miniaturized total analysis system (m TAS) were introduced in this paper. In addition to simple presentation of capillary electrophoresis separation on micro-fluidic chip, many other new micro-separation methods, such as extraction separation, membrane separation, chromatography, magnetic separation and so on, were demonstrated and evaluated in detail about their application in m TAS. Research works on micro-separation for m TAS were reviewed. The potential development in the field of micro-separation on m TAS was prospected.
