The invention relates to a sulfur isotope online determination system and method for hydrogen sulfide in natural gas, and the system comprises a natural gas sampling unit, a hydrogen sulfide rapid enrichment unit, a hydrogen sulfide automatic sample introduction conversion unit and a sulfur isotope determination unit. The online determination of the sulfur isotope composition of the hydrogen sulfide is realized. Meanwhile, the technical method provided by the invention is simple and convenient to operate, a chemical conversion process in a traditional method is omitted, and the time cost and experimental cost invested during analysis of the sulfur isotope of the hydrogen sulfide are greatly saved. 本发明涉及一种天然气中硫化氢的硫同位素在线测定系统和方法，该系统包括天然气采样单元，硫化氢快速富集单元，硫化氢自动进样转化单元以及硫同位素测定单元，通过硫化氢快速富集单元可对硫化氢常温静置物理吸附，实现了硫化氢硫同位素组成的在线测定。同时，利用本发明中的技术方法操作简便，省去了传统方法中的化学转化过程，极大地节省了硫化氢硫同位素分析时投入的时间成本和实验费用。
