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, …
