UV-Vis-NIR SpectroPhotoMeter

This instrument measures substances based on their absorption characteristics of ultraviolet, visible, and near-infrared light. The continuous spectrum emitted by the light source is dispersed by a monochromator and then irradiates the sample. The detector receives the intensity of the transmitted light and converts it into an electrical signal. By comparing the absorbance difference between the sample and the reference, qualitative and quantitative analysis of the substance is achieved. It is applied in fields such as color fastness testing of ink pigments, light transmittance detection of plastic films, and whiteness measurement of paper.
Selection
Select transmission or reflection accessories based on sample morphology; consider that the spectral range must cover the characteristic absorption peaks of the analyte; pay attention to the grating type and wavelength accuracy to ensure resolution; check baseline flatness and stray light indicators to guarantee signal-to-noise ratio; confirm that the sample chamber size meets detection requirements; evaluate automatic scanning speed and data processing functions to satisfy the detection workflow.
