A Secret Weapon For ultraviolet-visible spectrophotometer
Tungsten filament is employed because the supply of visible light. This sort of lamp is Employed in the wavelength array of 375 – 800 nm and addresses a wide range of wavelengths.A widely applied detector in UV-Vis spectroscopy could be the Photomultiplier tube. It consists of a photoemissive cathode (that's a cathode that releases electrons when
