摘　　要：基于实现电泳芯片的低电压分离的思想 ,介绍了一种电泳芯片低电压分离的模型 ,利用在分离通道上分段、交替、循环施加电压的方法产生高效分离电场。同时 ,依据该模型对这种低电压集成电泳芯片的控制系统进行了相关的设计与研究 ,提出了以 89C5 1单片机为基础的相应的控制电路的实现方案。初步实验表明 ,该电泳芯片的低电压分离技术是可行的 ,这将为毛细管电泳分析仪器的微型化、集成化。Based on the idea of the low voltage separation of the electrophoresis chip, a new separation model is presented by applying low voltage alternatively and cyclically along the separation channel, so that the high electric field can be provided. Meanwhile, according to this model, relevant design and study on the control system of electrophoresis chip were carried out and a scheme of the control circuit is presented, which is based on 89C51 MCU. The initial experiment shows that the new separation technique is promising , which gives a possible solution scheme for the micromation, integration and portable design of capillary electrophoresis instrument.
