Abstract: Sulfur is widely distributed in nature, with various valence states such as -2, -1, 0, +4, +6, etc. The common occurrence forms include sulfate, sulfite, thiosulfate, elemental sulfur. There are obvious differences in sulfur isotopic composition in different media and forms. The source and transformation process of sulfur can be traced through the difference of sulfur isotopic composition. Therefore, sulfur isotopic composition is widely used in the research of scientific problems in many fields such as ambient science, geochemistry,ore deposit geology, and geography. Sulfur isotope analytical technique is the basis of applied research on sulfur isotope composition. This paper reviews the sulfur isotope analysis technologies in the past ten years, and summarizes the basic principles, advantages and disadvantages, applicable sample types, research status and future development directions of different analysis methods, which provides reference for the research and application of sulfur isotope analysis and testing technology.
