Title: Implementation of Photoelectric Data Acquisition for Grating Biochemistry Analyzer
Abstract: This paper designed the photoelectric detection system for the grating biochemistry analyzer.Low-level and wide dynamic range currents were measured as well as the logarithmic operated by the new kind model of logarithmic amplifier Log114.It took high precision16bit A/D converters for data acquisition, meanwhile,used digital filter to delete random noise and pulse interface in software.By analyzing the measured result of known absorbance of several solution on 340 nm wavelength,the design of system was proved to be fully in line with the requirements of grating biochemistry analyzer.
