2、 Instrument parameters
2.1 Principle
The detection system of the detector consists of tungsten halogen lamp, deuterium lamp, multi-channel colorimetric dish sample cell, miniature spectrometer, linear CCD sensor, embedded microprocessor system and other components. It can directly display the content of harmful substances in the tested sample on the LCD screen and print out the analysis results. Using the latest national standard method and based on the principle of Lambert Beer law, quantitative analysis is carried out by comparing unknown concentration samples with known concentration standard substances. The expression of Lambert Beer's law is as follows: A=- log τ=abcIn the formula: A - absorbance of the substance; τ - transmittance of matter; A - absorption coefficient of the substance; B - Optical path length; C - the concentration of a substance.
