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 7900s quadrupole ICP-MS with an ESI NWR193 excimer laser-ablation system. We welcome both internal and external users. Contact Robert Holder (roholder@umich.edu) for information and pricing.
