Stationary source emissions. Determination of mass concentration of sulfur dioxide. Ion chromatography method Ingestion-build-100998 BS EN ISO 21649:2009 supersedes1 Scope This International Standard specifies a method for the determination of the mass concentration of sulfur dioxide emitted from combustion facilities and technical processes, and defines the most important performance characteristics. The method described in this International Standard has been tested for a sulfur dioxide concentration range of 6 mg m3 to 333 mg m3 with sampling periods of 30 min. It is applicable to mass concentrations of
