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.
