The Central Analytical Facility (CAF) at Stellenbosch University is a rather unique comprehensive core facility which employs approximately 40 members of staff supporting a wide range of analytical facilities. The CAF is organised into Units and Divisions which specialise in the following areas: Electron Microscopy; Fluorescence Microscopy and Flow Cytometry; ICP MS and LA ICP MS, including geochronology applications; LCMS including proteomics applications; GCMS; NMR including solid state applications; X-ray CT Scanning; Neuromechanical Analysis; PET/CT Scanning; DNA Sequencing; and Vibrational Spectroscopy. The aim of the CAF is to ensure optimal utilisation of expensive multi-user research equipment in the service of the research community at Stellenbosch University, and the South African research and development sector in general. The Electron Microscopy Unit houses state-of-the-art EM equipment, including a Zeiss Merlin FESEM with S-TEM, EDS, CL, SE, BSE and cryo capabilities, a Zeiss EVO MA15 analytical SEM which includes EDS, WDS, SE, BSE and a cryo stage, as well as a LEO Variable Pressure-SEM which includes SE, BSE and CL detectors. Additionally we house a Zeiss AxioImager with Zeiss's Shuttle-and-Find system for correlative imaging of light and electron microscopy (CLEM). The aim of the EM Unit is to support and advance imaging and analytical electron microscopy for all scientific disciplines at Stellenbosch University, as well as the broad scientific community throughout South Africa. We encourage and support international collaboration. This recruitment exercise seeks to enhance the capabilities of the unit in quantitative electron beam analysis of hard materials, with particular emphasis on the quantitative analysis of major, minor and trace elements in minerals and glasses.
