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.
Claims10
A characterisation cell for smoke analysis, by optical spectrometry comprising:
- a reaction chamber;
- an inlet orifice for the inlet of smoke inside the reaction chamber;
- an outlet orifice for the evacuation of smoke from the reaction chamber;
- an analysis window for entry of a laser beam intended to form the plasma inside the reaction chamber;
- wherein the cell further comprises:
- a fan for ensuring scanning of inert gas in the vicinity of the analysis window;
- and
- a coaxial shielding injector for shielded injection of smoke inside the reaction chamber, the shielding being ensured by a jet of inert gas around the smoke.
