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...
Energy-dispersive X-ray spectroscopy (EDS, also abbreviated EDX or XEDS) is an analytical technique that enables the chemical characterization/elemental analysis of materials. A sample excited by an energy source (such as the electron beam of an electron microscope) dissipates some of the absorbed...

EDS可以达到很高的空间分辨率(1 nm以下),但是能量分辨率一般都在100 eV以上。EDS通常也不能检测原子序数很低的元素(一般用来检测铝Al以上的元素),因为轻元素对应的X射线能量较低,而在低能区探测器的吸收背景干扰比较大。

EDS的话经常和电子显微镜结合在一起用。电镜一般有两种,扫描电镜(SEM)和透射电镜(TEM)。如果EDS用在SEM上,则是用来分析样品表面的元素;若是用在TEM上,则可以分析样品内部的化学组成。 EDS是用高能电子(SEM的话大概5-20keV,TEM的话60-300keV)轰击样品(也有不用电子而用质子或X射线的),样品中原子里的基态(grou...
Energy Dispersive Spectrometry (EDS) is a material characterisation technique used to identify which elements are present within a material. EDS measures X-rays that are generated from the interaction between the electron beam and a sample within an electron microscope. Detection and characterisation of...
