Abstract
A pneumatic nebulizer of the type used for aspirating a fine spray of a liquid analytical sample into the sample burner flame of an atomic absorption spectrophotometer or the like. The nebulizer comprises an atomizing venturi nozzle formed of corrosion-resistant material, the nozzle including a monolithic flexible tube having one end extending to a sample source and its other end terminating coaxially within an apertured nozzle member to define therewith an annular orifice through which high velocity gas flow occurs to aspirate sample liquid from the other end of the tube.
Claims4
In a nebulizer for forming a fine spray or mist from an originally liquid (sample) solution of the type including means for forming a venturi restriction including a narrow venturi throat through which a gas travels at accelerated velocity, and a nebulizing tube of substantially capillary size positioned with its tip within the narrow venturi throat, through which tube the sample solution is introduced and caused to nebulize into a fine mist at its tip by means of the high velocity gas flow through the narrow venturi throat in the vicinity of said tip so as to form a mixture of fine liquid mist and gas, the improvement comprising:
- said liquid nebulizing tube being in the form of a flexible monolithic corrosion-resistant artificial resin tubing, one end of which forms said nebulizing tip of said tube, while the other remote end is directly introduced into a container holding the original liquid sample solution.
