UV/Visible Spectrophotometer
Ultraviolet Double-Beam Spectrophotometer, Perkin-Elmer Lambda 3B with integrating sphere accessory.
The UV method is applied to organic analysis. Molecules with two or more isolated chromophores (absorbing groups) absorb light of nearly the same wavelength as does a molecule containing only a single chromophore of a particular type. The intensity of the absorption is proportional to the number of that type of chromophore present in the molecule.
