An electron microprobe has broad applications of imaging in the microfield, compositional spot analysis as well as mapping of the distribution of elements in minerals and inorganic synthetic substances. Chemical analysis is conducted in a micro-area, typically with a spot diameter from <1 to 5 µm of a beam focused on a polished sample. An electron microprobe allows to constrain chemical composition of any substance in the solid state.
Samples used in electron microprobe analysis are embedded in a rounded, polished epoxy mount with a diameter of approximately 25 mm (1 inch) or a microscopic thin section with dimensions of approximately 46 mm × 27 mm. The electron microprobe enables to perform quantitative analyses of major and trace elements (from 4Be to 92U, excluding noble gases) and chemical mapping of the distribution of elements using EDS and WDS techniques supported by the cathodoluminescence technique.
