dispersive X-ray spectroscopy (WDXRF or WDS) *A method used to count the number of X-rays *Reads or counts only the x-rays of a single wavelength *Element must be known *Often used in conjunction with EDS ** *Materials evaluation and identification *Contaminants *Elemental diffusion profiles...
Energy Dispersive X-Ray Spectroscopy (EDS or EDX) is a chemical microanalysis technique used in conjunction with scanning electron microscopy (SEM). (SeeHandbook section on SEM.) The EDS technique detects x-rays emitted from the sample during bombardment by an electron beam to characterize the ele...

Energy-dispersive X-ray spectroscopy (EDS, also abbreviated EDX or XEDS) is an analytical technique that enables the chemical characterization/elemental analysis of materials. A sample excited by an energy source (such as the electron beam of an electron microscope) dissipates some of the absorbed...
