Double-Beam UV-Vis SpectroPhotoMeter

The dual-beam UV spectrophotometer simultaneously measures the sample beam and the reference beam, utilizing the selective absorption characteristics of substances in the ultraviolet-visible light range to detect sample concentration or purity. It is applied in solution concentration determination, monitoring of chemical reactions, and substance identification, and is used for quantitative analysis in the fields of chemical engineering and environmental protection.
Selection
When selecting, consider a wavelength range covering 190-1100 nm, with a bandwidth of 1-2 nm to meet routine detection requirements. Focus on baseline stability and stray light indicators, and opt for an automatic eight-cell holder to enhance efficiency. Ensure the deuterium and tungsten lamps have matching lifespans, the sample compartment size accommodates experimental vessels, and the software includes spectral scanning and quantitative analysis functions.
