Description:
EPA source test methods for reduced sulfur compounds, Method 15 for Claus sulfur recovery plants and Method 16 for Kraft pulp mills have been evaluated, and information is provided for the user. Techniques and procedures for the gas chromatographic measurement of hydrogen sulfide, carbonoxysulfide, carbon disulfide, methylmercaptan, dimethylsulfide and dimethyldisulfide were studied. Absorption of these species on the surfaces of the chromatographic system was found to be the main source of imprecision and inaccuracy in the analysis. Permeation devices containing the above sulfur compounds were found to permeate at uniform rates after one year of use. Aluminum cylinders containing compressed gas mixtures of the compounds under investigation were analyzed for four months. Results showed them to be stable in some instances and to be promising candidates for quality assurance materials. Comparison of an electrolytic conductivity detector with a flame photometric detector showed the former to be valuable for the analysis of reduced sulfur compounds under laboratory conditions.
