WebThe UV-Vis spectral range is approximately 190 to 900 nm, as defined by the working range of typical commercial UV-Vis spectrophotometers. The short-wavelength limit for simple UV-Vis spectrometers is the absorption of ultraviolet wavelengths less than 180 nm by atmospheric gases. Purging a spectrometer with nitrogen gas extends this limit to 175 … WebUV-Vis spectroscopic instruments are used to identify, characterize, and quantify an extraordinary wide range of molecular compounds. It can be used for non-destructive …
