Large flat panel tester

Large flat panel tester principle

The analysis principle of the flat plate testing instrument is to use the selective absorption phenomenon of substances to different wavelengths of light for qualitative and quantitative analysis of substances. By analyzing the absorption spectrum, the structure and chemical composition of substances can be determined. Using a prism or grating to separate monochromatic light, the monochromatic light is continuously passed through a solution in sequence, and the absorption of each wavelength by the solution is measured to obtain the absorption spectrum curve.

This instrument operates based on the principle of relative measurement, which involves selecting a solvent (distilled water, air, or sample) as the reference solution and setting its transmittance (i.e., transmittance)T）For100%The transmittance of the tested sample is obtained relative to the reference solution. Transmittance (transmittance)T）There is a certain functional relationship between the changes in the concentration of the measured substance, and within a certain range, it conforms to the Lambert Beer law.

among whichTTransmittance ratio（ Transmittance rate

A： AbsorbanceC： Solution concentrationK： The absorbance coefficient of the solutionL： The length of the liquid layer in the optical path

I： The intensity of light passing through the test sample and shining onto the photoelectric converter

Io： The intensity of light passing through the reference test sample and shining onto the photoelectric converter
