Energy Dispersive X-Ray Spectroscopy (EDS)

 

How Does It Work?
An EDS system is used in conjunction with a Scanning Electron Microscope (SEM). The electrons that are used in imaging in the microscope sometimes interact with the electrons on the atoms in the sample being observed, which excites these electrons to a higher energy state. When the electrons drop back down to their base energy, they release x-rays of characteristic energy. Each element can only release electrons of certain energies, and so by examining the x-rays generated, it is possible to determine what elements are present and the relative concentration of those elements.
