Electron Micro Probe Analyzer
Methods IGW, Müller-Sigmund
| Electron Micro Probe Analyzer (EMPA) | Model: | Cameca SX 100 |
| Unit and Room: | Mineralogy, Lab Build., R. 01009 | |
| Responsible: | Dr. Hiltrud Müller-Sigmund | |
| Elemental Analysis by X-ray emission spectra | Further information: | http://www.minpet.uni-freiburg.de/sites/englisch/analytik/mikrosonde.html |
| Short Description: The EMPA allows nominally non-destructive, quantitative analyses of elements with Z>3 in solids; polished and conductive sample surface required (limited range of samples sizes, including 40mm round, 1 inch round, 48x28mm, max. thickness ca. 1 cm) | Picture of the Equipment
| |
| Available Experiments/Techniques: - quantitative analyses - element mapping - concentration profiles - (thin film and single particle analysis) | ||
| Special Equipment: 30 kV electron gun, W-filament | ||
| Measurements on the equipment are currently done by: | Students after extensive training Trained scientific service personal | |
| Recent Publications, where this instrument was important (citation): | Parat F. et al. 2010: Experimental constraints on ultrapotassic magmatism from the Bohemian Massif (durbachite series, Czech Republic). Contributions to Mineralogy and Petrology 159, 331-347. | |
| Typical problems that may be solved with this instrument: | element concentrations in solids, element distribution, thin film analysis | |
