3 terms and units of measure

The following terms and definitions apply to this specification. 3.1 automatic biochemical analyzer automaticchemistryanalyzer All analytical procedures (including filling of samples and reagents, mutual reactions, chemical and biological analysis, calculation of results, and The results were read out) automated biochemical analyzers were implemented. [YY/T 0654-20173.2] 3.2 absorbance absorbance The ratio of the transmitted light intensity to the incident light intensity is the transmittance, and the common logarithm of the reciprocal of the transmittance is called the absorbance. [YY/T 0654-20173.1]

4 Overview

The automatic biochemical analyzer (hereinafter referred to as the analyzer) is based on the characteristics of the measured substance in the ultraviolet and visible regions. The absorption spectrum follows the principle of Lange-Beer law and compares samples of unknown concentration to known concentrations of reference materials. Quantitative analysis is performed or according to the molar absorption coefficient method. The expression of Lange-Beer's law is as follows. A=-lg(I/I0)=-lgT=klc (1) In the formula. A---the absorbance of the substance; I0---incident light intensity; I---transmitted light intensity; T---the transmittance of the substance; k---the molar absorption coefficient of the substance, L·mol-1·cm-1; ......
