  • Apparatus and method for extracting gaseous, liquid and/or solid elements from a gaseous medium and concentrating them in a liquid medium
    Patent number: 7892336
    Abstract: The invention relates to an apparatus and to a method for extracting elements from a gaseous medium and concentrating them in a liquid medium, by nebulizing this liquid medium by means of the gaseous medium and condensing the mist produced by this nebulization. This apparatus comprises a first enclosure for nebulization and condensation, intended to contain the liquid medium, which is provided with a conduit for delivering the gaseous medium, means for nebulizing the liquid medium, and a conduit for discharging the gaseous medium, means for depressurizing or pressurizing the interior of the first enclosure, and is characterized in that it comprises a second enclosure for condensation and means for cooling this second enclosure.

    Assignee: Commissariat A L'Energie Atomique
    Inventors: Pierre Charrue, Gilles Thevenot, Goulven Cavalin, Roger Delmas
  • Installation and process for automatic preparation of samples
    Patent number: 7517698
    Abstract: An installation for the automatic preparation of specimens by liquid/solid extraction on a column is characterized in that the extraction device comprises, on either side of the columns (3), a valve (4) controllable to switch one column (3) to the other to actuate one column (3) adapted to ensure the extraction function when another column (3) is in a non-operating condition, each switching valve (4) being connected to a controllable common direction reversing valve (5) arranged to impose one direction of circulation on the fluid in anyone of the columns (3) of the extraction device and to ensure its return to the valve (5) to distribute the treated fluid toward a circuit selectively either for its rejection or for its analysis.
