| 发明名称 | Aerosol generator | ||
| 摘要 | A sonic aerosol generator is provided that provides a constant concentration of particulate aerosol over a long exposure time to an animal. The concentration of aerosols is maintainable for greater than 30 hours at concentrations of 15 mg/m3 or more. The aerosol generator is used to expose subject to high concentrations of aerosols that more accurately represents the levels that may be seen in a workplace environment. | ||

| 主权项 | 1. An aerosol generator comprising: an acoustic energy generator; an aerosol chamber; a first diaphragm having a first side and a second side, and coupled to said aerosol chamber, said first diaphragm being impenetrable to aerosol or substrate; said acoustic generator acoustically coupled to said first side of said first diaphragm, said acoustic generator generates acoustic energy of sinusoidally oscillating frequency; wherein the atmospheric pressure of a gas atmosphere on said first side or said second side of said first diaphragm is tunable. | ||
