| Abstract: | The fluid distribution in the micro channel of ICEC ( Integrated Capillary Electrophoresis Chip) was simulated using ANSYS software. The relations between the micro channel structure and flow velocity under different sample injection modes were obtained. Then the optimized channel structure was chosen by the width of 16μm , the depth of the chip was determined 10μm and the effective separation length of 3.5cm with round corner channel. The chip structure was designed. Using the principle of laser induced fluorescence, the detection system for this chip was set up. The experiment for the ICEC could realize the base line separation of two DNA restriction fragments ranging from 500bp to 1021bp with excellent resolution. The result of the experiment would be the stable groundwork for further research in ICEC. |
