Spectroscopy is the branch of science dedicated to the investigation of electromagnetic spectra produced from the interaction between a sample and an energy source.
In the quality assurance/quality control industry, optical emission spectroscopy (OES) plays a key role in material testing. The uses of OES cover a large scope of applications, but it is generally used for material identification and composition certification to industry specifications. Additional uses include homogeneity testing, determination of material contaminations or weld dilution, and failure analysis, among others.
Spectroscopy is the branch of science dedicated to the investigation of electromagnetic spectra produced from the interaction between a sample and an energy source. Optical emission spectroscopy is a specific type of analytical technique that focuses on the emission of light by atoms in the range of approximately 100-700 nm, which encompasses visible light as well as part of the ultraviolet range.
