Calibration and Method Validation for Neodymium (Nd) Isotope Ratio Measurements performing by ThermoFisher Neptune Plus Mass Spectrometer in the NEPTUNE-TIMS Laboratory (Istituto di Geoscienze e Georisorse, CNR di Pisa)

We describe here in detail the results and the setup of the high precision Nd isotope ratio analysis performed by Multi Collector Inductively Coupled Plasma Mass Spectrometer (MC ICP MS), Thermo Scientific Neptune Plus TM. Isobaric interferences and mass discrimination were corrected by using natural invariable 147Sm/144Sm and 146Nd/144Nd isotope ratios. We reported data on set of international certified standard materials (JNdi-1 and AGV-1) measured with MC-ICP-MS Neptune Plus, focusing on the accuracy and reproducibility of the analyses performed in the Neptune-TIMS Laboratory
