The scanning electron microscopy lab (SEM)

The purpose of the electron microscopy research is to study the morphology of organic material and to analyze the chemical composition, crystal structure and - orientation and microstructural features of rocks and microfossils down to the nano-scale in order to infer processes of evolution, environmental conditions, mineral reactions, phase transformations, and deformation.



The SEM lab hosts two Zeiss instruments:

  • One Zeiss Sigma field emission microscope for viewing and EDS analysis of biological and other organic material.
  • One Zeiss Merlin field emission microscope with EDS, WDS, CL, and EBSD equipment for mainly analytical and crystallographic work.


Resolution: 0,8 nm v/15 kV (MERLIN), 1,5 nm v/15 kV (ZIGMA).
