Abstract
An aerosol modulating nozzle with a nozzle body having a nozzle head cham and including aerosol sample flow inlet and outlets for transmitting aerosol sample through the nozzle head chamber. Also included is a sample discharge for discharging a small portion of aerosol in a predetermined direction along with a sheath of clean air. The quantity of sample discharged is modulated. Constrictions in the inlet and outlet flow tubes allow pressure fluctuations to be sustained in the nozzle head chamber. A loudspeaker operating into a closed chamber is used to generate pressure fluctuations which are transmitted to the nozzle head chamber.
