    Continuous emissions monitoring for H2S monitoring

    To monitor H2S can be difficult. The UV absorption is without structure and the IR absorption has strong interference from H2O. The traditional way has been to remove all SO2 from the sample while keeping H2S, then convert H2S to SO2 ,and finally measure SO2 which then effectively yields the H2S concentration. The instruments used have often been ambient air SO2 analysers and extractive dilution systems. However, it is not unusual to experience practical problems with these type of installations.

  • Portable Stack Monitoring

    Many industries are required to measure stack emissions of toxic gases periodically, but not continuously. Extractive wet chemical methods currently used are slow, labor intensive and expensive. A single GasFinderFC can perform stack monitoring requirements for a specific gas, quickly, easily and accurately.
