Abstract

A fully automated high-precision capillary electrophoresis instrument, comprising an electrophoresis system, a sample injection flow path, and an automatic sampling flow path; the sampling flow path comprising a shunt waste bottle, which is connected to a four-way connector, a four-way sample injection valve and a buffer syringe pump; the automatic sampling flow path comprises a sampling needle, a sample tray, a cleaning tank, reagent bottles, a buffer tube, a six-channel liquid dispenser, and a syringe pump. The described capillary electrophoresis instrument has a fast sample injection speed, high accuracy, good reproducibility, and can be widely used in automated analysis of different substances by capillary electrophoresis.
