Total Sulfur and Sulfur species. Total Sulfur shall be analyzed quarterly in a certified laboratory during the first year of supply. Sulfur species concentrations shall be identified and compared with the concentration of total sulfur. After typical values are determined and no corrosive sulfur is present - then the frequency can be lowered (twice a year in the second year and annually afterwards). If, however, concentrations greater than 6 mg/m3 of COS or RHS or any corrosive sulfur species (as S) shall be found at any time then total Sulfur shall be measured continuously using an ASTM standard (ASTM D7493 or ASTM D7165 – 10). A full laboratory Sulfur species analysis shall be performed with any significant change of gas quality.
