NEBULIZER WITH NANOMETRIC FLOW RATE OF A LIQUID EFFLUENT AND NEBULIZING INSTALLATION COMPRISING SAME

摘要

The invention concerns a nebulizer with nanometric flow rate of a liquid effluent in a nebulizing gas comprising at least, arranged substantially concentric, a capillary tube (6) for intake of the liquid effluent and a nebulizing needle (9) including a central channel (9b) fed with liquid effluent through the capillary tube (6), a chamber (4a) for intake of the nebulizing gas feeding a nozzle for expelling the nebulizing gas, the nebulizing needle passing through the intake chamber (4a) and the nozzle (4b) expelling the nebulizing gas, the nebulizing needle (9) including a outlet for the liquid effluent whereof the aperture diameter (F_a) is less than 20 ?m, the ratio of the diameter of the outlet of the nozzle (4b) expelling the nebulizing gas and the outlet (F_o) of the nebulizing needle being more than 10. The inventive nanometric flow rate nebulizer and nebulizing installation are applicable in mass spectrometry of trace elements contained in intracellular or microbiological medium for example.
