Optical Emission Spectroscopy

Optical Emission Spectroscopy can determine the specific elemental constituents of an alloy by showing the exact percentage of each element present in the test sample. 

 

OES is performed by heating the surface of the test material until it emits light. The emitted light is collected and then dispersed via prism. The resultant spectrum reveals the presence of specific elements by their characteristic wavelengths. The intensity of the elemental wavelength is measured to determine the ratio of the element to the rest of the alloy.
