The flat plate of the stage, called the impaction plate or collection plate, blocks the flow to form an abrupt bend in the streamlines. Particles whose inertia exceeds a certain value (cutoff size) will be unable to follow the streamlines and will impact on the collection plate and be deposited on it.

Andersen Cascade Impactor 8 Stage MDI Metered Dose Inhalers; DPI Dry Powder Inhaler Aerodynamic particle sizing. The design concept of the Andersen Cascade Impactor evolves from the following information: The human respiratory system tract is an aerodynamic classifying system for airborne particles.
Unlike the AGI-30, the Andersen six-stage impaction sampler provides accurate particle-size discrimination. It is described as a multilevel, multiorifice, cascade impactor (Jensen et al., 1992). The Andersen 6-STG was developed by Andersen in 1958 and operates at an input flow rate of 28.3 L min −1.
SIX-STAGE VIABLE CASCADE IMPACTOR The Six-Stage ACI is a multi-orifice, cascade impactor which is normally used to measure the concentration and particle size distribution of aerobic bacteria and fungi in the intramural or ambient air. This instrument has been widely used as a standard for enumerating the viable particles in a microbial aerosol.

The 8-stage Andersen Cascade Impactor (ACI) is the most frequently used instrument for the testing of inhaler products within the Pharmaceutical Sector. Westech ACIs are specifically designed to meet the highest criteria laid down in the various. Pharmacopoeias for characterising aerosol clouds emitted by inhalers.
