Energy dispersive spectrometry
WebFeb 11, 2024 · A detector is angularly scanned relative to the analyzing crystal, registering the spectrum. Energy Dispersive (ED): The entire polychromatic spectrum from the sample is incident upon a detector that is capable of registering the energy of each photon that strikes it. The detector electronics and data system then build the X-ray spectrum … WebFeb 20, 2024 · The high-energy electron beam of the scanning electron microscope (SEM) interacts with the sample material and a characteristic X-ray is generated. Energy-dispersive X-ray spectrometer (EDS, EDXS) then detects the characteristic X-ray. When a high-energy electron beam contacts the sample, the incident electron ejects an inner …
