Preferred Label : cascade impactor;
IUPAC definition : An instrument used for the classification of aerosols according to size and for possible
subsequent chemical analysis. Air is drawn through a series of orifices of decreasing
size; the air flow is normal to collecting surfaces on which aerosols are collected
by inertial impaction. The particles, separated stepwise by their momentum differences
into a number of size ranges, are collected simultaneously.;
