  • Method for producing monodisperse aerosols
    Patent number: 4963289
    Abstract: An aerosol generator is described which is capable of producing a monodisperse aerosol within narrow limits utilizing an aqueous solution capable of providing a high population of seed nuclei and an organic solution having a low vapor pressure. The two solutions are cold nebulized, mixed, vaporized, and cooled. During cooling, particles of the organic vapor condense onto the excess seed nuclei, and grow to a uniform particle size.
    Type: Grant
    Filed: June 8, 1989
    Date of Patent: October 16, 1990
    Assignee: The United States of America as represented by the United States Department of Energy
