Measurement of the Isotopic Composition of Uranium in Geological Samples by MC-ICP-MS Using a TOPO-Based Extraction Chromatographic Protocol
U values in excellent agreement with published data, demonstrating the accuracy and robustness of the protocol. Overall, this protocol enables the quantitative recovery of high-purity U and high-precision U isotope determination, providing an alternative to the double spike technique and promoting its wider application in geochemistry.
