稳定同位素稀释共振电离质谱法适用于碳质球粒陨石和铁陨石中铼锇丰度和锇同位素组成的测定。化学过程包括过氧化钠融合，然后从硫酸/过氧化氢中蒸馏锇，随后从同一溶液中阴离子交换分离铼。
A stable isotope-dilution method using resonance ionization mass spectrometry is suitable for the determination of rhenium and osmium abundances and osmium isotopic composition in carbonaceous chondrites and iron meteorites. The chemical procedure involves sodium peroxide fusion, followed by distillation of osmium from sulfuric acid/hydrogen peroxide and subsequent anion-exchange separation of rhenium from the same solution.
