Andersen Cascade Impactor (ACI) - Copley Scientific
Andersen Cascade Impactor (ACI) Cascade impactors operate on the principle of inertial impaction. Each stage of the impactor comprises a series of nozzles or jets through which the sample laden air is drawn, directing any airborne towards the surface of the collection plate for that particular stage.
