3 Overview

Silicate analyzer (hereinafter referred to as the instrument) is used to measure the water content of silicate analysis instrument that measures primary Water soluble silicon processing under certain conditions, the reagent reacts and color, according to Lambert - Beer law, when Bundle of parallel monochromatic light through the light-absorbing substance containing the colored solution, part of the light is absorbed when the absorbing layer thickness is not Varying proportional to the concentration and the absorbance of light-absorbing substance by photoelectric detection device converts the optical signal into an electrical signal by After the microprocessor, the display silicate content. Lambert - Beer law mathematical expression is. A = -lg I0 = - lgT = klc Where. A --- absorbance substances; I --- transmitted monochromatic light intensity; Monochromatic light intensity I0 --- incident; T --- substance transmittance; Extinction coefficient k --- substances; l --- analyte optical path substances; c --- concentration of the substance. Instruments mainly by the light source system, the spectrometer, the sample chamber, the detection system, etc., see Schematic figure 1. ......
