Our new LA-ICP-MS laboratory is used for trace-element analysis, mapping, and U–Pb petrochronology of rocks and minerals. Instruments:
—Agilent 7900s quadrupole ICP-MS.
—ESI NWR193 excimer laser-ablation system.
We are currently working on optimizing analytical procedures. If you are interested in using this facility or wish to discuss its capabilities, please contact Robert Holder.
More information to come soon.
