title: [Air humidity and their influence on concentration changes of spray fluid in aerosol generators (author's transl)].
abstract: With the fine dispersion of aqueous solutions concentration changes in the basic solution are occuring. These changes are basically dependent on the rate of air flow and the saturation deficit which is present between the air at the entry to the aerosol generator and its exit. Above all with compressed gases which are used in production of nozzle aerosols the deficit and with it the concentration change is large. But on ultrasonic generators this effect is to be observed too. Under normal manufacturing conditions a concentration increase in the spray solution occurs. Conditions resulting in a concentration decrease can rarely be expected.
