摘要
GB/T11060.1-1998“天然气中硫化氢含量的测定——碘量法”是分析气样中硫化氢含量的权威化学分析方法,其方法准确可靠,测量范围广。但是,在实验室和现场的硫化氢含量分析中,特别是在做现场天然气中硫化氢含量测定的比对分析时,有时其测定结果得不到良好的重复性、再现性。着重从溶液配制、取样、滴定操作三方面的细节入手,对气样中硫化氢含量分析进行相应阐述。
GBA/T1160.1—1998 “Measurement of Sulfureted Hydrogen Content in Natural Gas-Iodimetry” is a kind of authoritative chemical analysis method for determining hydrogen sulfide content in natural gas. This method is accurate and reliable, with wide measurement range. But in the lab, even in comparison analysis of determining content on the spot, the result is not as equal as usual. Expounded are details of compounding solution, sampling and titration operation to accord with precision requirements in national standards.
