Abstract:
An ionizer includes a probe having multiple coaxially aligned conduits. The conduits may carry liquids, and nebulizing and heating gases at various flow rates and temperatures, for generation of ions from a liquid source. An outermost conduit defines an entrainment region that transports and entrains ions in a gas for a defined distance along the length of the conduits. In embodiments, various voltages may be applied to the multiple conduits to aid in ionization and to guide ions. Depending on the voltages applied to the multiple conduits and electrodes, the ionizer can act as an electrospray, APCI, or APPI source. Further, the ionizer may include a source of photons or a source of corona ionization. Formed ions may be provided to a downstream mass analyser.

Claim (Index 1):
An ionizer comprising:\n an outer gas transport tube having an outlet in flow communication with an inlet to a mass analyser; an inner gas transport tube extending into said outer gas transport tube; an innermost analyte supply tube extending into said inner gas transport tube, and upstream of said outlet of said outer gas transport tube, the innermost analyte supply tube configured to provide droplets of solvated analyte, received by the innermost analyte supply tube from an analyte source, from a tip of said innermost analyte supply tube into said inner gas transport tube; and at least one voltage source interconnected with said outer gas transport tube, said inner gas transport tube, and said innermost analyte supply tube, wherein the voltage source is configured to provide a voltage to said innermost analyte supply tube to transport and guide solvated analyte to the tip of said innermost analyte tube to provide the solvated analyte into the inner gas transport tube, wherein the voltage source is configured to provide a voltage to said inner gas transport tube to spray, in a first gas, the solvated analyte received from the innermost analyte supply tube into the outer gas transport tube, and wherein the voltage source is configured to provide a voltage to said outer gas transport tube to ionize, in a second gas, the sprayed analyte received from the inner gas transport tube, and wherein said at least one voltage source is operable to maintain said outer gas transport tube, said inner gas transport tube and said innermost analyte supply tube at about equal potential offset from a potential of said inlet to the mass analyzer, to guide the ionized analyte from said ionizer to said inlet of said mass analyzer.
