The JEOL microprobe has been decommissioned. For analytical microprobe work please contact the Syracuse University user facility. This would be the tool to use for accurate WDS work, especially light element analyses. Their Cameca system is cleaner than our old microprobe and also has an Oxygen nozzle for cleaning surface contamination which is helpful for quantitative Carbon and Nitrogen analyses. The Cameca also has cathodoluminensence. We can provide small probe qualitative light element analysis and quantitative and qualitative analyses of heavier elements using EDS on the Mira and Zeiss SEMs here at Cornell.
