Abstract
An air sampler is designed for a predetermined flow rate. The air flow is admitted to at least two impactors operating in parallel. Preferably the inlet nozzles and the outlet orifices of each impactor are sized to achieve predetermined cut-off sizes of particles; preferably the composite curve of all the impactors will mimic a predetermined particle sampling efficiency curve.
