A sensitive and fast method for simultaneous determination of gaseous ammonia (NH3) and particulate ammonium (NH4+) in ambient air is presented. NH3 is sampled in a cylindrical wet effluent diffusion denuder (CWEDD) and analyzed on-line by continuous flow system with a fluorescence detector (FLD) while NH4+ bound to aerosol particles is sampled in parallel by a condensation growth unit – aerosol counterflow two-jets unit (CGU-ACTJU) sampler and analyzed on-line with another FLD.
