英文摘要：

The techniques for the sulfur isotope measurement by using MC-ICP-MS have been reported in this paper. The reference and sample preparation methods as well as the instrumental mass bias correction procedures have been introduced. In addition,the spectral interferences,matrix effects and concentration effects on the analytical results of the sulfur isotope measurement have been evaluated. Especially,the effects of matrices on both isotopic ratios and signal intensities have been explored and the sulfur concentration effect correction curve has been introduced in order to measure sulfur isotopes more rapidly by using MC-ICP-MS.
