Laboratory for electron beam microanalysis

Building T – Room T 033

Tel.: +49 30 - 838 - 70869

 

Contact person: Dr. Moritz Liesegang, Mail: m.liesegang@fu-berlin.de

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)

Tel.: +49 30 - 838 - 70824

 

Contact person: Dr. Anselm Loges, Tel. +49 30 - 838 - 71761, Mail: anselm.loges@fu-berlin.de

Equipment

The Raman laboratory is equipped with a “Horiba ISA Dilor Labram” micro-confocal Raman spectrometer with a focal length of 300mm and a spectral resolution of up to 3.5 cm-1.

Depending on the analysed material and the applied method, the user can choose between the internal 632 nm He-Ne and an external 532 nm Nd-YAG laser. Maps and linescans can be done with the automated x-y table.

 

Applications

  • Phase identification of fluids, minerals and partly glasses (Fingerprinting)

  • Structural (e.g.: stress-strain, metamictisation) and orientation effects

  • Carbon thermometry

Contact Persons:

Prof. Dr. Christiane Stephan-Scherb; Tel. +49 30 - 838 - 60497

Dr. Moritz Liesegang; Mail: m.liesegang@fu-berlin.de

Equipment

  • Two different tube types: Cu- tube and Co tube

  • Fixed divergence slit optics with different apertures from 1/16° - 2

  • 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.

  • Sample changer with a 15-position magazine.
