UV-VIS
Ultraviolet-Visible Spectroscopy (UV-VIS) is a frequently used tool in many fields of chemistry. Its use is central in a wide range of techniques, from simple colorimetric assays to complex biomedical experiments. Many organic or inorganic chemicals absorb light in the range of roughly 200-800 nm, depending on their electronic structure. The technique can be used to confirm the identity of a structure, but it is more frequently used to measure the concentration of substances in a mixture.
