What is the difference between EDX and EDS?

The standard EDX analyzers can detect elements with an atomic number from 11 (sodium) upward . The windowless EDX analyzer can detect elements from boron (atomic number 5) upwards, including the major elements present in tissues (carbon, nitrogen and oxygen).

SEM provides detailed high resolution images of the sample by rastering a focussed electron beam across the surface and detecting secondary or backscattered electron signal. An Energy Dispersive X-Ray Analyzer (EDX or EDA) is also used to provide elemental identification and quantitative compositional information.

Energy-dispersive X-ray spectroscopy (EDX) is a surface analytical technique where an electron beam hits the sample, exciting an electron in an inner shell , causing its ejection and the formation of an electron hole in the electronic structure of the element.

If you have wondered why EDS, EDX, and EDSX seem to be used interchangeably, that is because there is no difference in these terms . EDS, EDX, and EDXS refer to the same technique: Energy Dispersive X-Ray Spectroscopy. The most popular name for this technique is EDS, followed by EDX.
