OS GSO ISO 6326-3:2008 Scope
This part of ISO 6326 specifies a potentiometric method for the
determination of hydrogen sulfide, mercaptan Sulfur, and carbonyl
sulfide Sulfur in natura1 gas in the concentration range
equal to or above 1 mg/m3. The gas must be free of dust, mist,
Oxygen, hydrogen cyanide and carbon disulfide. The hydrogen
suIfide/mercaptan Sulfur ratio and also the mercaptan
sulfur/hydrogen sulfide ratio should not exceed 50 : 1.
The method is not recommended for gases containing more
than approximately 1,5 % ( Vl V carbon dioxide.
NOTE - In all Parts of ISO 6326, 1 m3 of gas is expressed at normal
conditions (0 “C; 101,325 kPaL
