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.

EDX (Energy-Dispersive X-ray spectroscopy)又稱為EDS (能量色散X-射線光譜)，其實是SEM (掃描電子顯微鏡)、TEM (透射電子顯微鏡)和STEM (掃描透射電子顯微鏡)分析技術下的一種附加功能。 EDX/EDS可以提供直徑小到奈米 (nm)尺寸區域的元素分析。 EDX/EDS使用X-Ray電子束對樣品撞擊以產生樣品元素的特性頻譜，達到單點的元素成分測定目的。 （對於大陸那些盜文網站，複製貼上本站文章後，居然還改成自己公司的名字，感到無恥！ 文章內容部份防止複製編排可能 …

开始的时候能谱的缩写有很多，比如EDS，EDX，EDAX等，大家对此也都心照不宣，知道ED就是Energy Dispersive，后面因为X-ray Analysis和Spectrum这几个词的不同用法，导致了缩写的不同。

We present a robust strategy to quantitatively assess elemental distributions in 3D nanostructured beam-sensitive samples. Key elements are resin embedding, and elemental co-localisation building on a combination of electron tomography and energy-dispersive X-ray spectroscopy.

2019年9月1日 · Quantitative chemical analyses of Ni 3 Al based hardening precipitates (γ′) in polycrystalline Ni based superalloys have been conducted using energy dispersive X-ray spectroscopy (EDX), coupled with a scanning transmission electron microscope (STEM).

edx量測出現多峰的原因關係到元素的電子層殼及其能階，建議可以先複習一下基礎化學，原子依照其原子序的大小會有不同的軌道(電子層)數，由內向外會有所謂的k(2顆電子)、l(8顆電子)、m(18顆電子)、n(32顆電子)、o(50顆電子)、p、q…等軌道層。

2018年7月5日 · Results showed that the Ni/ZSM5-30 catalyst generated the maximum syngas production of 100.72 mmol g−1plastic, followed by the Ni/β-zeolite-25 and Ni/Y-zeolite-30 catalyst. In addition, the ZSM-5 supported nickel catalyst showed excellent coke …

For thick TEM samples, k-factor correction due to X-ray absorption is needed in order to accurately quantify EDS measurements. Table 1825 lists Ni-examples of thicknesses at which the thin-film approximation is no longer valid due to X-ray absorption effects in specific materials.

A Ni-free surface with a protective 25 nm-thick titanium oxide film resulted from soaking mechanically treated samples of the NiTi wire in a saline solution for two years under static conditions.
