LA-ICP-MS lab

Our LA-ICP-MS laboratory is used for trace-element analysis, mapping, and U–Pb petrochronology of solid materials. The lab uses an Agilent 7900 quadrupole ICP-MS with an ESI NWR193 excimer laser-ablation system. We are not a commercial lab, but we welcome both internal and external users for collaborative research. Contact Robert Holder (roholder@umich.edu).
