  • Fine particle constituent measuring method and fine-particle constituent measuring apparatus
    Patent number: 7764373
    Abstract: Fine particles such as nanoparticles and microparticles is irradiated to generate plasma by focusing an ultrashort pulse laser beam 15 emitted from a laser device 16. More preferably, the plasma is generated by a filament 14 generated in the ultrashort pulse laser beam 15. A constituent of the fine particles is measured based on an emission spectrum from the plasma.
    Type: Grant
    Filed: September 20, 2006
    Date of Patent: July 27, 2010
    Assignee: Central Research Institute of Electric Power Industry
    Inventors: Takashi Fujii, Naohiko Goto, Megumi Miki, Takuya Nayuki, Koshichi Nemoto, Nobuyuki Tanaka
