Abstract
An ionizer disposed in an ionization chamber separated from an analysis chamber by a partition provided with an ion introduction port, the ionizer including: an electrospray ionization probe 111 configured to charge and nebulize a liquid sample as charged droplets, the electrospray ionization probe being disposed such that a nebulization axis is orthogonal to a central axis of the ion introduction port; and a heated gas supply mechanism configured to blow a heated gas to a position between a tip of the electrospray ionization probe and an intersection point X of the nebulization axis and the central axis, where the position is separated from the tip by a predetermined distance or more.
Claims5
An ionizer disposed in an ionization chamber separated from an analysis chamber by a partition provided with an ion introduction port, the ionizer comprising:
- an electrospray ionization probe configured to charge and nebulize a liquid sample as charged droplets, the electrospray ionization probe being disposed such that a nebulization axis is orthogonal to a central axis of the ion introduction port;
- and
- a heated gas supply mechanism configured to blow a heated gas, from a predetermined direction, to a position between a tip of the electrospray ionization probe and an intersection point of the nebulization axis and the central axis, the position being separated from the tip by a predetermined distance or more,
- wherein the predetermined direction and the predetermined distance are set such that the heated gas does not reach the electrospray ionization probe.
