【Abstract】 Since 1990s, microchip based capillary electrophoresis has been highlighted dramatically in the field of μ TAS. In this paper a novel integrated microchip based capillary electrophoresis system with electrochemical detection is described. To fit this detector, a new method was developed to fabricate 30 μm Pt microdisk electrodes. Based on the end column mode, the system was employed to separate three kinds of neurotransmitters within tens of seconds.更多还原
