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...

Energy dispersive spectroscopy is used to perform a localized chemical assessment by evaluating the X-ray spectrum released from a sample inundated by a focused ray of electrons. All elements from Beryllium (atomic number 4) to Uranium (92) can be detected with the technique, but some devices ...
With improvements in energy-dispersive spectroscopy (EDS) there has been a grow- ing misunderstanding that scanning elec- tron microscope EDS is an adequate substi- tute for electron probe microanalysis (EPMA) and some blurring of the under- standing of the limits of quantification of SEM-EDS, ...

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。
