Glycosylated hemoglobin（GHb or HbA1c）detector is the core component of fully automated glycated hemoglobin detector.Applied the principle of UV/visible absorption photometer

the HbA1c detector for HbA1c levels detection based on ion-exchange chromatography is designed.The detector is divided into signal acquisition and data processing and display module.Signal acquisition module

includes LED light source

flow cell

photoelectric conversion and A/D conversion section.The ARM9 hardware platform centralized on S3C2440 is developed for data processing and display.It consists of SDRAM

NAND Flash

RS232

SPI

LCD display and 4-wire resistive touch screen module.Based on the hardware design

the detector control software based on embedded Linux operating system is designed.This system has advantages of high sensitivity

good anti-interference ability and good real-time performance.
