  • Method and apparatus of classifying fine particles
    Patent number: 7732725
    Abstract: A method of classifying fine particles includes: introducing a fine particle dispersion containing the fine particles to a micro flow channel having an inlet part and a collection part from the inlet part; moving the fine particles to an inner upper side of the micro flow channel by an electric field applied in a gravitational direction; and delivering the fine particle dispersion in a laminar flow state to the collection part. The delivering step includes classifying the fine particles according to differences in settling velocity among the fine particles.
