Description

The Institute of Geological Sciences hosts a JEOL JXA 8200 Superprobe equipped with five wavelength-dispersive spectrometers (WDS) and one energy-dispersive (EDS) detector. We perform non-destructive chemical analysis and imaging of solid materials at the micrometer scale using a focused electron beam. The instrument is primarily used in WDS mode for quantitative analysis against reference materials and element distribution mapping. Other applications are: qualitative element analysis (EDS, WDS), surface morphology (secondary electron detector), element contrast imaging (backscatter electron detector, EBSD). User regulations can be found here.

Instruments

An electron microprobe is an electron microscope designed for the non-destructive x-ray microanalysis and imaging of solid materials. It is capable of high spatial resolution and relatively high analytical sensitivity. [Source: Caltech] (Source: Global Change Master Directory (GCMD). 2023. GCMD Keywords, Version 16.3 [...] )
