Abstract:
An aspirator/nebulizer-based fluid transfer system comprising:an elongated sprayer tube having an inlet end and an outlet end; a nebulizing tube at the outlet end of the sprayer tube for directing nebulizing gas having a flow rate past said outlet end; a make-up tube for supplying make-up fluid having a flow rate to a fluid transfer region adjacent said inlet end; a source of analyte provided at a spaced distance from the inlet end; and, means for adjusting the nebulizing gas flow rate and the make-up fluid flow rate to form a free-standing junction coupling the sprayer tube and the source of analyte, whereby said nebulizing gas causes aspiration of the make-up fluid and the analyte into and through said sprayer tube via the free-standing junction, and nebulizes fluid flowing out of said outlet end of said sprayer tube.
