Description
The Electron Microprobe lab offers non-destructive chemical analyses of solids using a JEOL JXA-8200 Electron Probe Microanalyzer (EPMA) with an EDX detector. The microprobe is capable of quantitatively measuring the abundance of all elements from C to U using five wavelength-dispersive spectrometers (WDS) and an energy-dispersive X-Ray spectrometer (EDX) for rapid analyses. This analytical technique combines micron-scale chemical analyses with scanning electron microscopy and is capable of large- and small-scale element mapping of specimens. The microprobe is equipped with a cathodoluminescence-, secondary electron- and backscattered electron-detector and a pointlogger system.
