  • Smoke analysis characterization cell
    Patent number: 9733189
    Abstract: The invention relates to a smoke analysis characterization cell employing optical spectroscopy, which comprises: a reaction chamber, an inlet orifice for injecting smoke into the reaction chamber; an outlet orifice for discharging the smoke from the reaction chamber; and an analysis window for the entry of a laser beam intended to form the plasma inside the reaction chamber, which cell is characterized in that the system further includes a blower for blowing an inert gas close to the analysis window; and a shielding gas injector for the shielded injection of the smoke into the reaction chamber, the shielding being provided by a jet of inert gas around the smoke.
