Abstract

Results of a high throughput, robust and sensitive method for the precise analysis of 87Sr/86Sr by Multi-Collector-Inductively Coupled Plasma-Mass Spectrometer (MC-ICP-MS), Thermo Scientific Neptune PlusTM are reported. The data were obtained after accurate procedures of chemical separation and purification of Sr from geological matrices such as silicates, sulfides, carbonates and waters, using Eichrom Sr-spec resins as well as the routine for Sr isotope measurement. Mass discrimination and instrument drift were corrected by using natural constant 86Sr/88Sr ratios as an internal standard. Data on set of international certified standard materials (SRM NIST 987 and AGV-1) as well as intra-lab reference samples (water sample KGV-9) measured with MC-ICP-MS Neptune Plus, focusing on the accuracy and reproducibility of the analyses performed in the Neptune-TIMS Laboratory are here reported.
