Double-beam UV-Visible SpectroPhotoMeter

A double-beam UV-Vis spectrophotometer divides the light source into sample and reference beams for synchronous measurement, allowing real-time subtraction of background interference. It is used to detect the absorbance of substances in the ultraviolet-visible light region, making it suitable for measuring solution concentrations, testing material purity, and monitoring chemical reaction processes.
Selection
When selecting, ensure the wavelength range covers 190–1100 nm, and choose the spectral bandwidth according to detection accuracy requirements. Verify baseline flatness and noise indicators, and confirm that the sample chamber size accommodates the detection containers. Consider automatic wavelength calibration and dual-detector configurations to ensure long-term instrument stability meets daily testing frequency demands.
