Scope

This guideline presents a method for the determination on the mass concentration of gaseous ammonia in ambient air. Due to the low ambient concentrations of ammonia, active accumulating sampling is used. Here a selective separation of gaseous ammonia using the principle of diffusion is described. The measurement method for ammonia in ambient air described here can be used in the range of mass concentrations up to 25 ?g/m3 (as monthly average). According to the measurement task and type of sampler, hourly to monthly average values can be determined with decreased sampling duration for higher concentrations too.
