This work presents the first combination of the MICAP ion source with a multi-collector mass spectrometer and the first characterization of the resulting MC-MICAP-MS instrument for high-precision Sr isotope abundance ratio measurements.
This study presents a method for high-precision isotopic analysis of K and Rb using the Neoma MC-ICPMS/MS with a collision/reaction cell, enabling simultaneous analysis of both K and Rb isotopes from a single sample aliquot.
Thermal ionization mass spectrometry is considered as the “gold standard” for obtaining precise 87Sr/86Sr isotopic ratios.
This review covers advances in atomic spectrometric techniques, including atomic emission, absorption, fluorescence and mass spectrometry. Material on speciation and coupled techniques is not covered as this is included in a separate ASU review.
Rb–Sr beryl geochronology provides an independent chronometer capable of delivering robust age constraints, with significant implications for geochemical investigations and gemstone provenance studies.
