UV-Visible-NIR SpectroPhotoMeter

UV-Visible-NIR spectrophotometers emit a continuous spectrum from a light source, which is then separated into specific wavelength beams by a monochromator. After the sample absorbs the light, a detector measures the intensity of the transmitted light. They are used for qualitative and quantitative analysis of substances, such as detecting dye concentrations and pollutant levels in the chemical and environmental protection industries.
Selection
Select UV, visible, or infrared models based on the sample absorption band; consider spectral bandwidth and wavelength accuracy to match detection requirements; verify baseline stability and noise indicators; confirm that the sample cell type is compatible with liquid and solid testing; evaluate software functionality and data output formats.
