Nebulizer with nanometric flow rate of a liquid effluent and nebulizing installation comprising same
Résumé
The nebulizer with a nanometric flow rate of a liq. effluent in a nebulizing gas comprises at least, arranged substantially concentrically, a capillary tube for intake of the liq. effluent and a nebulizing needle including a central channel fed with liq. effluent through the capillary tube, a chamber for intake of the nebulizing gas feeding a nozzle for expelling the nebulizing gas, the nebulizing needle passing through the intake chamber and the nozzle expelling the nebulizing gas, the nebulizing needle including a outlet for the liq. effluent whereof the aperture diam. (Φa) is <20 μm, the ratio of the diam. of the outlet of the nozzle expelling the nebulizing gas and the outlet (Φo) of the nebulizing needle being >10. The nanometric flow rate nebulizer and nebulizing installation are applicable in mass spectrometry of trace elements contained in intracellular or microbiol. medium for example.
