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