The electron microprobe technique allows for nondestructive analyses of smallest parts of materials (in micrometer range) with high precision. Materials that can be analyzed are embedded and polished mineral grains (also gemstones), glass particles as well as rocks. Except for H, He, and Li all elements of the periodic table until including U can be detected and quantified. The GFZ maintains two electron microprobes, a JEOL Hyperprobe JXA-8530F PLUS with a field emission (FE) electron gun and a JEOL Superprobe JXA 8230 with a tungsten or LaB₆ cathode. The facility is available for GFZ employees as well as for external users / research groups. For sample preparation and user regulations please see here.
