ICP-MS ANALYTICAL TECHNIQUES

The cornerstone of the geochemical focus is the ICP-MS lab. We have developed new techniques for accurate and precise determinations of high field strength elements (Zr, Nb, [Y], Hf, Ta, Th, U), an important group for determining petrogenetic models, and also the platinum group elements (Ru, Rh, Pd, Pt, Os and Ir: PGEs). The PGEs are present in ultra-trace abundances in geological materials (parts-per billion or less) so require careful analysis.  All of my students are required to master ICP-MS analytical techniques.
