Stationary source emissions - Determination of ammonia (NH3)

Le présent document décrit une méthode manuelle de mesurage de la concentration en ammoniac présent dans les effluents des conduits de sources fixes. Deux techniques analytiques sont proposées : la chromatographie d'échange d'ions et la spectrométrie d'absorption moléculaire. Il s'applique à des effluents gazeux plus ou moins chargés en poussières et dont la concentration en NH3 peut varier entre 0,1 mg/m3 et 200 mg/m3 dans les conditions normales de pression et de température.
