本方法用于测定贫胺溶液中的硫代硫酸盐。硫代硫酸盐计算并报告为表观H2S（单位:格令/gal）或硫代硫酸钠（单位:g/100ml）。检测下限约为25格令/gal。

This method is for determining thiosulfate in lean amine solutions. Thiosulfate is calculated and reported as either apparent H2S in grains/gal or as sodium thiosulfate in g/100 mL. The lower limit of detection is approximately 25 grains/gal.
