Energy-Dispersive X-Ray Spectroscopy (EDX)
EDX is sometimes called EDS or EDAX analysis. It is an analytical technique used for the elemental analysis or chemical characterization of an area if interest on a specimen. This analysis equipment works as an integral feature of a Scanning Electron Microscope (SEM) and can not function on its own without the later.
The output of an EDX analysis is an EDX spectrum plot. An EDX spectrum plot identifies the elements corresponding to each of its peaks. An EDX spectrum normally displays peaks corresponding to the energy levels or which the most X-rays had been received. Each of these peaks are unique to an atom, and therefore corresponds to a single element. The higher a peak in a spectrum, the more concentrated the element is in the specimen.
