the different structure models of microchip electrophoresis are set up
and the fluid flow situation in the microchannel are simulated with the CFD software at the different design parameter and the voltage combination.The final simulation results indicate that the shape of sample injection on the microchip electrophoresis is the rectangle
the width of the microchannel is 20μm
the electric field strength of the sample injection and separation is between 200
2
50V/cm.Also a kind of spiral microchannel mode is optimized with the better separation efference in order to increase the efficiency separation distance on the limited microchip area.
