摘要：

The absolute S-32/S-34 ratios of IAEA-S-1 reference material and V-CDT standard are determined. For cross-checking, two sets of synthetic isotope mixtures are prepared from high purity S-32 and S-34-enriched materials in different forms: the first set is prepared from BaSO4 whereas the second is prepared from Ag2S. The sulfur,isotope analyses are done by using SF6 method with a MAT-251 EM mass spectrometer. The resulting 32S/34S ratio Of IAEA-S-l reference material is 22.656 4 +/- 0.006 0, and that of V-CDT is 22.649 6 +/- 0.006 0.
