Nova NanoSEM 230

The FEI Nova NanoSEM 230 was installed in December 2009.

The system is equipped with an EDAX Apollo X silicon drift detector energy dispersive X-ray spectroscopy (EDS) system.

The instrument is also outfitted with an electron backscattered diffraction (EBSD) system, which allows for crystallographic determination on the nanoscale, and, along with imaging capabilities, 3-D reconstructions of the material and crystallography.
