초록

A compact air sampling impactor assembly has an inlet nozzle overlying an impaction plate that is mounted on a flat housing that defines an interior chamber covered by a filter. An air flow outlet tube leading from the chamber is connected to an air pump and a flow is established through the nozzle so the air impinges on the impaction plate to leave particles thereon and the flow then passes through the filter to the chamber and then out the air outlet. The size is kept small for personal use. Cascade impactors can be made using additional flow paths def...
