Ultraviolet-Visible SpectroPhotoMeter

UV-Vis spectrophotometers utilize the absorption characteristics of substances to ultraviolet and visible light to measure the concentration of components in a sample. A light source emits a continuous spectrum, and a monochromator isolates light of a specific wavelength, which passes through the sample before a detector records the absorbance. This method is used for quantitative analysis of dyes and additive content, as well as for monitoring colorfastness and component stability in the coatings and inks industry.
Selection
Select the instrument's spectral bandwidth based on the absorption wavelength range of the sample, ensuring that the detection sensitivity matches the sample concentration. Pay attention to baseline stability and noise levels to ensure measurement repeatability. Choose a cuvette suitable for the sample morphology and verify whether the automatic sampling and data processing functions meet the daily detection requirements.
