Dual-wavelength UV spectroPhotoMeter

The dual-wavelength UV spectrophotometer irradiates the sample simultaneously with two beams of ultraviolet light at different wavelengths, measuring the difference in absorbance between the two wavelengths. It is used to eliminate background interference and detect the effects of turbid samples or coexisting substances. It is suitable for determining the concentration of ink pigments, monitoring wastewater, and analyzing the purity of polymers.
Selection
When selecting, consider matching the sample characteristics with the detection wavelength range, compare spectral bandwidth parameters based on detection accuracy requirements, select cuvette specifications based on the typical sample volume, ensure instrument stability meets continuous detection requirements, and evaluate whether the operation interface aligns with the users' habits.
