  • Methods for detecting sulfur
    Patent number: 9417227
    Abstract: A method for rapid detection of sulfur in a gypsum sample by causing emission of sulfur from the sample as vapors, reacting the vapors with silver nitrate and detecting sulfur by monitoring for color change. A kit for rapid detection of sulfur in a gypsum sample is also provided. Further methods include those in which the amount of sulfur in a gypsum sample is quantified in colorimetric analysis with silver nitrate and gypsum standards with known concentrations of sulfur.
