Ammonia is an important basic trace constituent in the atmosphere. A review with 52 references is given on the progress of sampling technology for atmospheric ammonia, including its theory, interference, (error) source, advantages and disadvantages and its applications. Filter packs method, diffusion denuder (method) and several kinds of automatic ammonia analyzers are described in detail.
