Micro-high voltage power system for capillary electrophoresis was an important part of Chip-based capillary electrophoresis.In the paper,a high voltage power system for capillary electrophoresis made use of three high voltage modules was designed whose core was STM32F103.In order to make the output steadier,this system used PID algorithm to regulate output of high voltage modules.The injection voltage,separation voltage, injection time and separation time can be set through keyboard.Real-time monitoring of ...
