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...
SEM方面:(EDS作为SEM的一个配件,EDX的探头伸进SEM的真空腔内) 加速电压HV/EHT:通常需要有一个过压比,即加速电压必须大于特征X谱线能量,通常是2~3 倍;对于轻元素,比如F,C等,一般用5KV,而对于金属元素则需要20KV; 探针电流/束流/束斑尺寸(SpotSize / Beam Current):让灯丝处于饱和状态以获得稳定的束流; 光...
available, rapid identification often can be made using a Scanning Electron Microscope (SEM) equipped with an Energy Dispersive X-ray Spectrometer (EDS) (Figure 1.1).SEMs have become fairly common laboratory instruments, and over half of them are equipped with an EDS (Goldstein et al., 2003)...

XPS是用已知固定波长(即固定能量)的X射线(X-ray)轰击样品,把样品中原子里的电子撞出来,然后测量撞出电子的动能以及拥有某一动能值的电子数。这样我们可以得到一个能谱图。通过测量入射X-ray与图中峰值对应的动能之差,我们可以确定样品原子中电子的结合能(bindingenergy)。然后可以查一查这个结合能与哪种元素电子的...
