Thiosulfate in Lean Amine Solutions
|Publication Date:||29 July 2002|
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.
