天然气.用气相色谱法测定硫化合物的含量

[中文适用范围]： 本标准规定了气相色谱法（GC）测定硫化氢、硫化羰、C1至C4硫醇、硫化物和四氢噻吩（THT）的方法。 根据附录中所选择的方法，硫化合物测定的应用范围可能有所不同，但无论使用哪种方法，都适用本国际标准的要求。 [外文原描述]： ISO 19739:2004 specifies the determination of hydrogen sulfide, carbonyl sulfide, C 1 to C 4 thiols, sulfides and tetrahydrothiophene (THT) using gas chromatography (GC). Depending on the method chosen from those given in its annexes, the application ranges for the determination of sulfur compounds can vary, but whichever of the methods is used, its requirements apply.
