MI-Chron 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 or user facility, but we welcome users for collaborative scientific research. Contact Robert Holder ([email protected]).
