Characteristic features of separation of aerosol particles when testing instruments for monitoring the cleanliness of industrial air

We determine the requirements for devices for size-fractionation of aerosol particles. We consider separation methods and devices used for such methods and give their comparative characteristics, and we point our their advantages and disadvantages. We determine the methods which are suitable for obtaining rest monodisperse aerosols by separating out particles of one size from polydisperse aerosols.
