Elemental and isotopic measurements and analysis of natural geomaterials
At the GISMO Facility, all the equipment is at the cutting edge of technology. We can offer organic and inorganic sample preparation, and analysis in two areas: (1) elemental and isotopic geochemistry and (2) X-ray diffraction of natural materials.
