New sampler for continuous determination of soluble fraction of atmospheric aerosols
Mikuška, Pavel ; Večeřa, Zbyněk
A new sampler, enabling continuous sampling of atmospheric aerosols by deionized water, was developed. Using fast and sensitive detection methods, the analysis of water soluble aerosol components is possible on-line, in real time with low time resolution. By the combination of the sampler and the anular diffusion denuder, the interferences of gas pollutants are elimined. The aerosols withparticle diameter > 0.3 .mi.m are quantitatively collected at flow rates of air 5 l/min, and water 0.5 l/min, respectively. The applicability of the sampler was successfully verified.
