Multiple gas flow ionizer
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.
