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...
