impaction plates for andersen cascade impactor

Cascade Impactor an overview ScienceDirect Topics

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.
