The FCS 249 is a combination of aerosol generator, volume flow unit, drying unit and distributor. Schematic depiction of the functional principle of FCS 249 (DUT – device under test). When producing test aerosols from aqueous solutions, initially a droplet aerosol is generated via a two-substance nozzle. Subsequently, this is passed through a dry atmosphere, which removes the moisture from the streaming aerosol by diffusion. In the case of salt solutions, an undisturbed, homogeneous crystallisation is thereby ensured, leading to the formation of compact, completely dried salt particles.
