Optical Emission Spectroscopy, or OES, is a reliable and extensively used analytical technique used to establish the elemental composition of a wide range of metals.
The type of samples which can be analyzed using OES include samples from the melt in primary and secondary metal production, and in the metals processing industries bolts, tubes, wires, rods, plates and so on.
OES uses the part of the electromagnetic spectrum — the visible spectrum and part of the ultraviolet spectrum. That’s from 130 nanometers up to around 800 nanometers, in terms of wavelength.
OES is capable of analyzing a wide range of elements from Lithium to Uranium in solid metal examples covering an extensive concentration range, providing low detection limits, high precision, and very high accuracy.
The elements and concentrations that can be determined by OES analyzers depend on the material being tested and the type of analyzer used. https://www.azom.com/article.aspx?ArticleID=15632
