【摘要】 多通道毛细管电泳芯片检测系统的性能决定其并行检测的精度及可行性。本文搭建了一种以CCD(TCD1304AP)为光电转换器件的多通道毛细管电泳芯片检测系统,可同时采集四个毛细管电泳通道的荧光信号。CCD器件将光电转换后的信号变为模拟信号,再通过高速A/D转换,经USB接口发送到上位机进行实时显示。系统具有检测精度高、体积小、自动化程度高、实时性强等优点。更多还原

【Abstract】 Performance of detection system of capillary array electrophoresis microchip determines the accuracy and feasibility of parallel detection.A detection system based on CCD(TCD1304AP) as photoelectric device was introduced in which four-channel fluorescent signals could be collected synchronously.Photoelectric conversion was implemented by CCD.The analog signals were transformed to digital signals by high-speed A/D device and then sent to host computer by USB interface for real-time display.The results showed that the system had advantages of small size,higher automation and precision,strong real-time character and so on.更多还原
