Laboratory of Scanning Microscopy of Biological and Geological Sciences Faculty of Biology and Earth Sciences Jagiellonian University Universitas Jagellonica Cracoviensis Division of Field Emission Scanning Electron Microscopy and Microanalysis at the Institute of Geological Sciences 30-063 Kraków, ul. Oleandry 2a; Poland www.uj.edu.pl/LabFESEM Division of Field Emission Scanning Electron Microscopy and Microanalysis at the Institute of Geological Sciences is equipped with modern cold field emission scanning electron microscope (FESEM) HITACHI S-4700 and energy dispersive spectrometer (EDS) NORAN Vantage. Analytical possibilities: • Magnification up to 500 000 x, • High resolution imaging (1.5 nm at 15 kV or 2.1 nm at 1 kV and 12 mm working distance), • two SE (secondary electrons) detectors (upper and lower) with energy filter, possibility of mixing of SE and BSE (backscattered electrons) signals, • Backscattered electrons detector (YAG BSE; TV mode), • Cathodoluminescence detector, • EDS system for spot chemical analysis, line scan, and mapping of elements distribution, • 45o specimen tilt, • Digital image acquisition (as JPEG, TIFF and BMP files) FESEM – EDS system can be applied for high magnification observation of various objects and chemical analysis with high spatial resolution, e.g.: • Morphology and chemical composition of components of rocks, soils, industrial products and wastes, biological materials, • Observation of structure of rocks, soils and sediments, • Analysis of morphology and chemical composition of atmospheric dust and aerosols, • Analysis of chemical composition of archaeological artefacts, • Analysis of composition of pigments, glasses, tissues, paper, metals in conservation of objects of cultural heritage. FESEM – EDS system is very efficient; software is user-friendly. Preparation of analytical documentation is very easy. Facilities for samples preparation are also available in the Laboratory. FESEM –EDS laboratory offers two scholarships for Ph. D. or M. Sc. Students in the field of Earth sciences (10 hours of free access to FESEM-EDS + samples preparation + technical assistance).
