Abstract

The invention provides a high-voltage power supply system for a capillary electrophoresis chip. The high-voltage power supply system comprises a relay array module, and a high-voltage module, an amplification-filter circuit, an analog/conversion circuit and a microprocessor, which are sequentially arranged, wherein the high-voltage module is connected with the relay array module; the microprocessor is provided with an input unit and an output port. By adoption of the scheme, the high-voltage power supply system has the advantages that a conventional high-voltage power supply module is improved, the high-voltage power supply system suitable for the capillary electrophoresis chip is provided, the volume can be further reduced, the voltage output stability is improved, and the high-voltage power supply system has extremely high application values.

Description

technical field [0001] The present invention relates, in particular, to a high-voltage power supply system for a capillary electrophoresis chip. Background technique [0002] Capillary Electrophoresis (CE) chip is an important part of Microfluidic System (Microfluidic System), which has the advantages of low cost, less sample consumption, fast analysis speed and high sensitivity. It uses a microcapillary as a separation channel, powered by a DC high-voltage power supply, and applies a voltage across the separation channel to achieve separation according to the characteristics of the sample to be measured. For example, the characteristics include charge, mass, polarity, and affinity. Due to the miniaturization and integration of capillary electrophoresis chip detection and analysis system, there is an urgent need for a high-voltage DC power system with small size and stable function. [0003] Some patents disclose the method that the capillary electrophoresis chip adopts a D...
