Principle
The instrument works based on the UV-Vis Spectrophotometric method, spectrophotometry principle. The composite light emitted by the light source is separated by a monochromator (using Czerny-Turner structure, focal length 160mm, equipped with 1200 gr/mm grating) to obtain monochromatic light of a specific wavelength. The monochromatic light passes through a dual-beam of light optical path system, one beam passes through the sample, and the other beam is used as a reference. The light intensity signals of the two beams are received by the import Detector and converted into electrical signals, which are processed and calculated by the circuit system. Finally, information such as the transmittance, Absorbance or concentration of the sample are obtained.
Applications
Daily analysis, scientific research
Steps
1. Boot initialization.
