Aerodynamic Assessment for Inhalation Products ...

The impactor or impinger is made of a series of four to eight tightly sealed stages. Each impactor stage is characterized by a nozzle or a set of nozzles and an impaction plate [5]. Like the ACI, the most recently developed impactor (the NGI) consists of eight stages. The aerosol particles are accelerated through nozzles to an impaction plate.

VARIABILITY IN CASCADE IMPACTION: SOURCES, IMPACT AND ...

INTRODUCING CASCADE IMPACTION Cascade impactors separate a sample by particle inertia, which is a function of particle size and velocity. During testing, sample laden air is drawn through the stages of the impactor at a constant volumetric flow rate by a vacuum pump (Figure 1). Each stage consists of a plate with a

Typical cascade impactors consist of a series of nozzle plates, each followed by an impaction plate: each set of nozzle plate plus impaction plate is termed a stage. The sizing characteristics of an inertial impactor stage are determined by the efficiency with which the stage collects particles of various sizes.
