Whether measuring chromatic properties of foodstuffs, analyzing wastewater quality according to standard procedures, or verifying the concentration and purity of a drug's active ingredient: UV/Vis spectroscopy is the right method for these applications. This spectroscopic method plays a role in every industrial sector, but especially in pharmaceuticals, environmental engineering, and the chemicals and foodstuffs industry. Here, spectrophotometers are an integral part of special applications and routine analyses, where they are used to ascertain the properties and concentration of individual atoms, molecules, or ions.
Spectroscopy refers to a number of physical methods that use electromagnetic radiation to investigate material properties such as electron transfers or vibrational states in samples. To this end, UV/Vis spectroscopy exploits the interactions of molecules with electromagnetic energy (molecular spectroscopy). This spectroscopic method is thus one of many types with a number of sub-methods:
- Atomic absorption spectroscopy (AAS)
- Molecular spectroscopy (UV/Vis, NIR, fluorescence, NMR)
- Atomic emission spectroscopy (OES)
- X-ray spectroscopy (XRS, XRF)
