Abstract:
1. A nebulizer with nanoscale flow rate of a liquid effluent in a nebulizing gas, said nebulizer including at least, arranged approximately concentrically: a capillary tube for intake of said liquid effluent and a nebulizing needle comprising a central channel fed with liquid effluent by said capillary tube; and a chamber for intake of said nebulizing gas feeding a nozzle for expelling said nebulizing gas, said nebulizing needle passing through said intake chamber and said nozzle for expelling said nebulizing gas, said nebulizing needle comprising an outlet orifice for said liquid effluent of which the opening diameter is less than 20 μm, the ratio of the diameter of the outlet opening of said nozzle for expelling the nebulizing gas to the outlet orifice of the nebulizing needle being greater than 10, wherein said capillary tube and said nebulizing needle are mounted in a male part, substantially symmetrical relative to a longitudinal axis of said nebulizer, said male part comprising a longitudinal bore equipped with a radial seat for supporting and holding said capillary tube and said nebulizing needle, said radial seat comprising a central orifice allowing the engagement of said capillary tube and said nebulizing needle and the abutment of the central channel of the latter, and wherein said capillary tube and said nebulizing needle are held in position centered within said bore via sleeves made of a flexible material that rest respectively against the opposite faces of said radial seat.
