Laboratory equipment

Scanning Electron Microscope Quanta^TM 650 FEG

• only high resolution FEG-SEM with ESEM technology
• charcterize conductive and non-conductive samples
  with SE and BSE imaging possible in every mode of operation
• minimize the amount of sample preparationj, low vacuum an ESEM capabillity enables charge-free imaging and analysis of non-conductive and/or hydrated specimens
• increase analytical capabilities by enabling EDS and EBSD analysis on conductive and non-conductive samples in high and low vacuum 
• perform dynamic in situ analysis of diverse samples in their natural state
• enable surface imaging with optional beam deceleration mode to get surface and compositional information from conductive samples
• MAPS
            - software for automated acquisition of high resolution images from large areas
            - enables the navigation, tiling, stitching, correlation and analysis of image data
• contact: Dr. Cordula Vogel
