Accurate and Precise Sulfur Analysis using the Flash Smart ...

to high amounts, was checked by the analysis of three samples at low, medium and high sulfur concentrations. For the low range a Soil Reference Material (0.0140 S%) was used; for the medium range, sulfanilamide standard (theoretical 18.62 S%, accepted range ±0.2) was chosen for analysis. For the high range, sulfur powder was chosen (99.98 S%).

Elemental Sulfur - an overview | ScienceDirect Topics

M.B. Goldhaber, in Treatise on Geochemistry, 2003. 7.10.3.5 Elemental Sulfur. Elemental sulfur is an oxidation product of dissolved sulfide. It may form inorganically, but in near-surface marine sediments where dissolved sulfide exists close to the sediment–water interface, it commonly forms because of the metabolic activities of sulfide oxidizing bacteria.
