SULFUR ISOTOPE RELATIVE RATIOS DETERMINED BY MASS SPECTROMETRY

摘要

The ratio of the sulfur isotope ratio, 34S/(32S + 33S), in a sample of sulfur hexafluoride to that in an isotopically different sample (relative ratio) is determined to ± 0.00003 (standard deviation) at relative ratios of 1.003-1.007 and near-natural isotopic abundances.
