Abstract
In an ionization device for an ionization chamber () separated from an analysis chamber (-) by a partition wall having an ion introduction port (), an ionization probe () sprays a liquid sample. A heated-gas supply mechanism (), which includes a gas supply source and a heating section () for heating a gas supplied from the gas supply source, expels the gas in a direction intersecting with the direction in which the liquid sample is sprayed from the ionization probe. A controller () controls an operation of the heated-gas supply mechanism so that the gas is continuously expelled from the heated-gas supply mechanism regardless of the presence or absence of an operation by a user while the liquid sample is sprayed from the ionization probe. The continuous expulsion of the gas from the heated-gas supply mechanism prevents this mechanism from being contaminated by the sprayed liquid.
