FIELD: the invention is designed for usage in meteorology, biology, chemical industry for controlling pollution of the environment.
SUBSTANCE: the essence is in that the precipitation of aerosol particles out of laminar isokinetic flow is made on two plates with collodion coverings. The collodion covering is applied on the front side of the first plate and on the rear side of the second plate. The intaking of aerosol particles is secured by regulating the distance between the plates in prescribed interval of their dimensions.
EFFECT: increases accuracy.
