  • Publication number: 20240274423
    Abstract: A method for full Os isotope static measurement by NTIMS includes steps of: selecting and weighing rock samples, and dissolving the rock samples to obtain dissolution liquid; chemically separating Os from the dissolution liquid to obtain purified Os solution; loading the purified Os solution on a Pt filament to obtain a sample to be determined; selecting Faraday cups and ion counters, as well as 1012? and 1013? amplifiers in NTIMS based on natural abundances of different Os isotopes, thereby establishing a cup configuration for the full Os isotope static measurement; establishing a yield calibration method for ICs; performing full Os isotopes static measurement based on the yield-calibrated ion counters and gain-calibrated faraday cups; and processing analytical data to obtain a final data of Os isotopic composition. The method enables the determination of the full Os isotope and oxygen isotope compositions of low-content or small-size samples.
