Abstract
A nebulizer and method for forming a finely atomized aerosol are provided. A first aerosol is formed by passing a gas jet across the mouth of a liquid channel that communicates with a liquid reservoir. The first aerosol then strikes a stop surface and is converted into a second, more finely atomized aerosol. The second aerosol impacts a buffer plate. The larger liquid particles in the second aerosol strike the plate and are either broken up or returned to the liquid reservoir. The smaller particles follow a labyrinthine path through at least one slit-shaped passage in the buffer plate, in the process forming a third, final aerosol. Selection of the passage size allows control of the particle size distribution of the third, final aerosol.
