For best results, the H2S-1100 Hydrogen Sulfide Converter should be used in conjunction with an ECOTECH Sulfur Dioxide analyser. Because H2S is oxidised to SO2 at 350 °C, and there is no conversion of other sulfur compounds, an accurate quantitative measurement of H2S in the atmosphere can be easily made.
