摘　　要：低电压驱动阵列电极式毛细管电泳芯片是针对毛细管电泳芯片分离电压高、系统体积庞大的缺点,在原有芯片的结构上进行改进的电泳芯片。通过建立数学模型,计算了设置阵列电极后毛细管电泳微沟道内的电势分布,并与常规进样条件下微沟道内的电势分布进行比较,结果表明该方法可以使分离电压大幅度下降。The low voltage-driven electrophoresis chip is a kind of capillary electrophoresis chips (CE chips) which makes some improvements on its original high separation voltage and huge system by using arrayed-electrode. It reports potential distribution around the channel after setting electrodes, by means of numerical calculation. Comparing with the potential distribution of CE chips, the separation voltage of low voltage-driven arrayed-electrode electrophoresis chips can be reduced considerably.
