Laboratory for electron beam microanalysis
Building T – Room T 033
Tel.: +49 30 - 838 - 70869
The Institute of Geological Sciences hosts a JEOL JXA 8200 Superprobe, equipped with five wavelength-dispersive spectrometers (WDS) and one energy-dispersive spectrometer (EDS). 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)

PIXcel 1 D detector. This is a semiconductor detector, which detects on 255x255 pixels, so very fast measurements are possible. The detector can be used in energy discriminating mode, optimizing the sensitivity for Cu-Ka radiation and efficiently suppressing any fluorescence radiation that may occur in samples containing Fe.
