Abstract
A new method for generation of aerosol particles, which will be called “boiling method,” is proposed. This method consists of (1) suspending particles in a liquid, (2) passing the suspension through a heated capillary tube, and (3) boiling of suspension to generate an aerosol. Aerosol particles thus generated are found to be effectively dispersed into primary (not coagulated) particles in high concentration. Such a dispersion is difficult if not impossible to produce by conventional nebulizers.
