Particle induced X-Ray Emission (PIXE) is a rarely used mineralogical analytical method. PIXE is used for laterally resolved detection and quantification of trace elements. The limits of detection are considerably better compared to the electron probe micro analysis (EPMA).
The Ion Beam Analysis Group at the Helmholtz-Institute Freiberg for Resource Technology uses several PIXE methods in close collaboration with the Ion Beam center (IBC) of the Helmholtz-Zentrum Dresden-Rossendorf to analyse minerals. We use a PIXE micro beam device as well as a new detector type a pnCCD detector, a so-called X-ray colour camera.
The analysis of minerals, embedded in epoxy resin like particle mounts or thin sections is greatly affected by instability under the influence of the proton beam. On this account a new embedding agent on a mineral base is necessary to develop.

The objective of the thesis is a systematic literature research for potential embedding agents on a mineral base as well as the validation of beam stability of these materials.
