Abstract: An ion source includes: an atomizer configured to continuously introduce a liquid sample and atomize the liquid sample; a heating and mixing chamber configured to vaporize the atomized liquid sample; and a charge supply unit configured to ionize the vaporized liquid sample. The charge supply unit has a positive pressure with respect to the heating and mixing chamber. The vaporized liquid sample and a gaseous seed ion supplied from the charge supply unit are mixed in the heating and mixing chamber. An auxiliary gas for adjusting a gas flow rate in the heating and mixing chamber can be introduced into the heating and mixing chamber. The heating and mixing chamber has a chamber outlet configured to introduce the ionized liquid sample into a mass spectrometer. The chamber outlet is connected to a first pore of the mass spectrometer.
