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.
能量散射X射線譜 （Energy-dispersive X-ray spectroscopy，英文縮寫有 EDS 、 EDX、EDXS 或 XEDS ），有時也被稱作 能量散射X射線分析 （ energy dispersive X-ray analysis ， EDXA ）或 能量散射X射線微量分析 （ energy dispersive X-ray microanalysis ， EDXMA ）是一種用於 元素分析 和 化學表徵 的分析手段。 該手段通過收集 X射線機 或其他X射線源產生的 X射線 和樣品交互作用時發出的X射線進行分析。 由於不同 元素 因原子結構不同而 發射譜 各異，所以可以通過分析X射線譜分辨樣品所含的不同成分 [2] 。
2019年11月28日 · By Antonis Nanakoudis 11.28.2019. From searching for food contaminants to identifying machine malfunctions to predicting how an aircraft part will corrode over time, energy-dispersive X-ray (EDX or EDS) analysis is a widely employed technique by today’s materials scientists.
Energy-dispersive X-ray spectroscopy (EDX or EDS) is an analytical technique used to probe the composition of a solid materials. Several variants exist, but the all rely on exciting electrons near the nucleus, causing more distant electrons to drop energy levels to fill the resulting “holes.”
Energy dispersive X-ray (EDX) analysis is a microanalytical technique for the quantitative analysis of elements that uses a characteristic spectrum of X-rays. In principle, when an electron beam impinges on a sample it ejects the secondary electrons from an inner shell and the vacancy generated gets filled up by the higher shell electrons.

2018年1月1日 · Abstract. The Energy Dispersive X-ray (EDX) microanalysis is a technique of elemental analysis associated to electron microscopy based on the generation of characteristic Xrays that reveals the presence of elements present in the specimens. The EDX microanalysis is used in different biomedical fields by many researchers and clinicians.
What is energy-dispersive X-ray spectroscopy? Energy-dispersive X-ray spectroscopy (abbreviated as both EDS and EDX analysis) is a powerful analytical technique used to identify and quantify the elemental composition of materials. It is a non-destructive method that is commonly used in conjunction with scanning electron microscopy (SEM).
