Energy dispersive x ray spectroscopy eds or edx wavelength dispersive x ray spectroscopy wdxrf or wds if. Spectroscopy is the study of how electromagnetic radiation and matter interacts. The subject of this project is about energy dispersive xray fluorescence edxrf. Energy dispersive spectroscopy eds was performed to compare the chemical composition of the alleged oxide product with that of the polished cut surface and also with other areas of the fracture away from the origin. Eds principle energy dispersive xray spectroscopy eds or edx is a qualitative and quantitative xray microanalytical technique that provides information on the chemical composition of a sample for elements with atomic number z 3. The eds technique detects xrays emitted from the sample during bombardment by an electron beam to characterize the elemental composition of the analyzed volume.
