Optical Emission Spectrometer, Principle and Latest Industrial Applications

Optical Emission Spectrometer (OES) has become a valuable, versatile and universal equipment for the chemical analysis of metallic alloys. Typical parameter ranges include detection of 37 elements with 41 channels (for five bases including Fe, Cu, Zn, and Ni & Al). A high voltage spark/arc is used as a source for the excitation of sample in an inert environment. The radiations emitted by the sample are analyzed by PMT (photomultiplier tubes) acting as detector. Principle, working and the latest applications of the equipment are also discussed. Application of emission spectrometer in the field of production and fabrication, manufacturing areas, steel industry, surgical industry, auto industry and product development sector is also highlighted.
