1. An ionizer, comprising:

  • a nebulizer configured to eject a liquid sample into atmosphere at atmospheric pressure to form a nebulized flow of the liquid sample;

    an electroconductive capillary disposed at a position forward in a flow direction of the nebulized flow formed by the nebulizer;

    a liquid supply configured to provide a liquid through the electroconductive capillary; and

    a power supply configured to apply a voltage to the electroconductive capillary, whereinthe nebulizer includes;

    a nozzle configured to eject the liquid sample; and

    a heater configured to dry the liquid sample ejected through the nozzle, andfirst components in the liquid sample are ionized by atmospheric pressure chemical ionization through corona discharge generated by the voltage applied to the electroconductive capillary by the power supply.
