Infrastructure belongs to:

For characterization of pores and fractures within rocks the laboratory is equipped with an X-Ray computer tomography system (Nanotom CT), He-gas pycnometer (AccuPyc), Hg porosimeter (2000 WS), and a gas adsorption porosimeter (TS Surfer). For damage-free preparation of 1 - 2 mm² large, almost planar surfaces, a broad ion beam (BIB) polisher operating with an Ar-Ion beam is operated.

  • Broad Ion Beam Polisher

    Broad Ion Beam (BIB)-Polierer (Jeol IB-19520CCP), der mit einem Ar-Ionenstrahl zur beschädigungsfreien Präparation von 1–2 mm² großen, nahezu ebenen Oberflächen arbeitet. Dies ermöglicht eine hochauflösende REM-Analyse von feinkörnigem Material wie Ton und Schiefer, einschließlich detaillierter Untersuchungen der Textur und des Porengefüges.

  • Porosimeter
  • Pycnometer

    High precision He-gas driven pycnometer for non-destructive measurement of matrix volume of rocks (AccuPyc, micromeritics)

  • X-Ray Computed Microtomography System

    Measurement method based on the transmission of X-Rays to obtain three-dimensional images of a sample. (Source: IUPAC; https://doi.org/10.1515/pac-2019-0302)
