A number of physical phenomena, in addition to the electron interactions used for imaging, take place at the sample surface. Generally they are narrow and readily resolved, but many elements yield multiple peaks. Energy-dispersive X-ray spectroscopy (EDS, also abbreviated EDX or XEDS) is an analytical technique that enables the chemical characterization/elemental analysis of materials. Because the energy difference between two specific orbital shells, for a given element, is always the same (i.e. Samples up to 8 in. Matching pixels are then displayed in the composition map. MultiScan acquires multiple scans of the line of the linescan. characteristic of that particular element), the photon emitted when an electron moves between these two levels will always have the same energy.

As secondary electrons are generated for imaging, the interacted atom becomes ionized and must capture an outer shell electron to return to the ground state. About 1 µm lateral resolution is possible. When an incident X-ray strikes the detector, it creates a charge pulse that is proportional to the energy of the x-ray. Therefore, by determining the energy of the X-ray peaks in a sample’s spectrum, and by calculating the count rate of the various elemental peaks, it is possible to qualitatively establish the elemental composition and to quantitatively measure the concentration of those elements.
