EDS分析是利用元素的特征X射线，而氢和氦原子只有K层电子，不能产生特征 X 射线，所以无法进行成分分析...
X-ray photoelectron spectroscopy enables XPS surface analysis, providing elemental composition and the chemical/electronic state of the top 10 nm of a material.
X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA), is a technique for analyzing a material’s surface chemistry. XPS can measure elemental composition as well as the chemical and electronic state of the atoms within a material. ...
我们为什么说ESCA,是XPS的另一种形式,电子光谱的化学分析,我们用XPS是为了分析样品表面的化学环境,化学分析,所以ESCA它对应的就是最早期的XPS,虽然他们的符号不一样,但是意义是一样的。这是X射线从我们腔体出发,打到样品表面,然后会产生光电子,电子是怎么来的? 3楼2023-10-15 07:19 回复 _奈文摩尔 光子的...
XPS analysis X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA), is a highly surface-sensitive, quantitative, chemical analysis technique that can be used to solve a wide range of materials problems. XPS is the measurement of photoelectrons ejec...

XPS也叫ESCA（ElectronSpectroscopyforChemicalAnalysis），是研究表面成分的重要手段。原理是光电效应（photoelectriceffect）。1960’s由UniversityofUppsala,Sweden的KaiSiegbahn等发展。EMPA中X射线穿透大，造成分析区太深。而由于电子穿透小，深层所产生的电子不出现干扰，所以可对表面几个原子层进行分析。（吸附、催化、...
简而言之，XPS是用X射线打出电子，检测的是电子；EDS则是用电子打出X射线，检测的是X射线。
