High precision Sr, Nd and Pb isotopic analyses using the new generations Thermal Ionization Mass Spectrometer ThemoFinnigan Tritonti

Abstract

The new generation Thermal Ionisation Mass Spectrometer (ThermoFinnigan Triton-Ti R ) and a clean lab for sample preparation have been established in Firenze in the last few years. Our research group has carried out the calibration of the analytical methods and the technical procedures to be applied in a number of geological research fields. In this contribution, we present the analytical procedures set up in the Radiogenic Isotope Geology Laboratory of Firenze with particular attention to the instrumental methodologies utilised in order to obtain high performances in terms of precision and accuracy on the measurement of Sr, Nd, and Pb reference samples.
