Energy-dispersive X-ray spectroscopy (EDS, EDX, EDXS or XEDS), sometimes called energy dispersive X-ray analysis (EDXA or EDAX) or energy dispersive X-ray microanalysis (EDXMA), is an analytical technique used for the elemental analysis or chemical characterization of a sample. It relies on an interaction of … See more Four primary components of the EDS setup are 1. the excitation source (electron beam or x-ray beam) 2. the X-ray detector 3. the pulse processor See more EDS can be used to determine which chemical elements are present in a sample, and can be used to estimate their relative abundance. EDS also helps to measure multi-layer coating thickness of metallic coatings and analysis of various alloys. The … See more • Elemental mapping • Scanning electron microscopy • Transmission electron microscopy • X-ray microtomography See more The excess energy of the electron that migrates to an inner shell to fill the newly created hole can do more than emit an X-ray. Often, instead of X-ray emission, the excess energy is transferred to a third electron from a further outer shell, prompting its … See more There is a trend towards a newer EDS detector, called the silicon drift detector (SDD). The SDD consists of a high-resistivity silicon chip where electrons are driven to a small collecting anode. The advantage lies in the extremely low capacitance of this … See more • MICROANALYST.NET – Information portal with X-ray microanalysis and EDX contents • Learn how to do EDS in an SEM – an interactive learning environment provided by Microscopy Australia See more WebWavelength dispersive spectrometry (WDS) is the older and rarer cousin of the widely used energy dispersive spectrometry (EDS) technique for elemental analysis in the scanning electron microscope (SEM).
