The application of inductively coupled plasma sector field mass spectrometers (ICP-SFMS), inductively coupled plasma quadrupole mass spectrometers with hexapole collision cell (HEX-ICP-MS) and multiple collector ICP-MS (MC-ICP-MS) for the determination of isotopic composition of highly enriched Os-187 and osmium samples is. described. Good agreement of isotopic abundance was found in the three applied methods. A precision. (2RSD) of 0.21-0.001, 0.83-0.09 and 5.5-0.083% for osmium. isotope ratios, depending on isotope abundance in an interlaboratory metallic osmium. sample, was observed in MC-ICP-MS, ICP-SFMS and HEX-ICP-MS measurements, respectively. A (NH4)(2)OsCl6 (specpure Johnson Matthey Chemicals, JMC) sample was also analyzed by the MC-ICP-MS. The measured osmium isotope composition of the metallic osmium and JMC sample corresponds to natural osmium. known in literature, with Os-187 abundance of 2.3 at.%. Os-187 abundance in three highly enriched samples of not identified, but assumed to be from special geological Precambrian formation of Russian origin varied between 98.934 and 99.53%. In addition, the Os-186/Os-192, Os-188/Os-192, Os-189/Os-192 and Os-190/Os-192 isotope ratios in all three enriched samples were close to the natural isotopic composition. This may indicate radioactive decay of Re-187 to Os-187 in rhenium-rich osmium samples in which the original osmium with a low initial concentration was of natural isotopic composition.
