Laser Ablation Split Stream (LASS) simultaneously measure U-Pb (or trace element) using the Element2 HR-SF-ICPMS and isotope compositions (e.g., Lu-Hf, Sm-Nd, Rb-Sr) using the Neptune Plus Multi-Collector ICPMS at RIGL.
We routinely analyze
- U-Pb (or trace element) and Hf isotopes in zircon
- U-Pb (or trace element) and Nd isotopes in REE minerals (e.g., monazite, titanite, apatite, allanite, chevkinite, etc.)
- Trace element and Sr isotopes in otolith.
Example of a zircon laser Hf session:
