Measurement of ammonia in ambient air - Sampling with diffusive samplers - Photometric or ion chromatographic analysis

Title (German)

Messen von Ammoniak in der Außenluft Probenahme mit Passivsammlern Fotometrische oder ionenchromatografische Analyse

Brief description

This guideline describes a procedure for the determination of mass concentration of gaseous ammonia in ambient air. An accumulating diffusive sampler is used for sampling because of the marginal ammonia concentration in ambient air. The measurement procedure for ammonia in ambient air described in this guideline is applicable in the mass concentratin range of 1 µg/m3 to 150 µg/m3 (as monthly average). Depending on measurement task and sampling type, the determination of hourly average to monthly average is also possible at higher concentrations when the sampling duration is shortened.
