IAEA和中国的硫同位素参考物质的δ^(33)S、δ^(34)S值与^(32)S/^(33)S、^(32)S/^(34)S绝对比值

The δ^(33)S and δ^(34)S Values and Absolute^(32)S/^(33)S and^(32)S/^(34)S Ratios of IAEA and Chinese Sulfur Isotope Reference Materials

用六氟化硫法对IAEA S 1、IAEA S 2、IAEA S 3、IAEA SO 5、IAEA SO 6、GBW 0 44 14和GBW 0 44 15的δ3 3 S、δ3 4 S值进行了测定。用人工配制的同位素混合物和六氟化硫法对IAEA S 1、IAEA S 2、IAEA S 3和GBW 0 44 14、GBW 0 44 15的3 2 S 3 3 S、3 2 S 3 4 S绝对值进行了标定。其结果对IAEA硫同位素系列参考物质的定值起到了关键作用。

The δ 33S、δ 34S values of IAEA-S-1、IAEA-S-2、IAEA-S-3、IAEA-SO-5、IAEA-SO-6、GBW-04414、GBW-04415 were measured with SF6 method. The absolute 32S/ 33S and 32S/ 34S abundance ratios of these samples were determined by using SF 6 method and with synthetic isotope mixtures. These data have played important role in determining theδ 33S、δ 34S values of IAEA series sulfur isotope reference materials.
