Electron probe microanalysis and microscopy Mineral inclusions Chromite Kimberlite Diamond deposit Electron probe microanalysis and microscopy is a widely used modern analytical technique primarily for quan- tifying chemical compositions of solid materials and for mapping or imaging elemental distributions or surface. Electron spectroscopy is an analytical technique to study the electronic structure and its dynamics in atoms and molecules. In general an excitation source such as x- rays, electrons or synchrotron radiation will eject an electron from an inner- shell orbital of an atom. Electron probe microanalysis ( EPMA) is an analytical technique that has stood the test of time. Not only is EPMA able to trace its origins back to the discovery of X- rays at the end of the nineteenth century, but the first commercial instrument appeared over 50 years ago. Nevertheless, EPMA remains a widely used technique for determining. Electron Probe Microanalysis: A Review of the Past, Present, and Future. Microscopy and Microanalysis:.

Electron microscopes work by using an electron beam instead of visible light and an electron detector instead of our eyes. An electron beam allows us to see at very small scales because electrons can also behave as light. What is an electron microprobe?
