What is ISO 21877- Stationary source emissions - ammonia about?
ISO 21877 discusses stationary source emissions with a focus on the mass concentration of ammonia. ISO 21877 specifies a manual method of measurement including sampling and different analytical methods for the determination of the mass concentration of ammonia (NH3) in the waste gas of industrial plants, for example, combustion plants or agricultural plants. All compounds that are volatile at the sampling temperature and produce ammonium ions upon dissociation during sampling in the absorption solution are measured by this method, which gives the volatile ammonia content of the waste gas.
ISO 21877 specifies an independent method of measurement, that has been validated in field tests in a NH3 concentration range of approximately 8 mg/m3 to 65 mg/m3 at standard conditions. The lower limit of the validation range was determined under operational conditions of a test plant. The measurement method is used at lower values depending, for example, on the sampling duration, sampling volume, and the limit of detection of the analytical method used.
