Abstract: Measurements of paniculate ammonium and gaseous ammonia in ambient air were studied by denuder difference and filter packs. The denuder difference experiment can be used to measure particulate ammonium and gaseous ammonia in the atmosphere while avoiding losses of particulate ammonium by sampling artifacts.
