Description:

Shared analytical facility specialized in areas of radiogenic isotope geochemistry, non-traditional stable isotope geochemistry, and low blank concentration determinations of natural and engineered materials. Provided equipment includes triple-quad ICP-MS (Agilent 8900) with laser ablation intake system (AS RESOlution laser system), multi-collector ICP-MS (Neptune Plus), and specially designed Picotrace metal-free low particulate clean laboratory. Produces high quality isotopic and trace element data. Offers training.
