Electron microscope

The big science of tiny things!
IOS has recently acquired a Zeiss scanning electron microscope (SEM) combining the analytical abilities of a QEMSCAN, an MLA and a microprobe. This high performance device has a host of applications that could complement your project by providing answers that no other micro-analytical technique can offer!
At the cutting edge of technology, it can carry out fast and accurate chemical analyses on every type of dry samples (mineral fragments, thin sections, drill core, soils, etc.) metallic or not, delicate or polished. Our laboratory will take care of sample preparation: mounting the grain or rocks in epoxy discs, making thin sections and the use of double-sided tape.
The range of specialised software for applied mineralogy creates chemical maps covering the entire surface of the sample for each element from beryllium to uranium as well as the mineral classification or texture description. The SEM also carries out imaging with a resolution of a few nanometres.
