Abstract: In the ionizer of the present invention, a stream of gas spouted from a nozzle (18) of a DART ionization unit (10) vaporizes and ionizes the components in a sample (25). Gaseous sample-component molecules which have not been ionized by that process are subsequently ionized by a reaction with a reactant ion produced by a corona discharge generated from a needle electrode (20). Such a two-stage ionization of the sample-component molecules improves the ionization efficiency. A needle-electrode support mechanism (21) adjusts the position and/or angle of the needle electrode (20) and thereby controls a potential gradient. Therefore, a specific sample-derived ion species can be efficiently introduced into an ion introduction tube (31) and be detected with a high level of sensitivity.

Abstract: A first mass analysis is executed in a condition that gas is not introduced into a loop-flight chamber (4), and a time-of-flight spectrum obtained in a data processor (12) is stored in a storage unit (13). Next, a second mass analysis is executed on the same sample as the one used in the first mass analysis in a condition that a valve (8) is opened and helium gas (He) is introduced into the loop-flight chamber (4), and the time-of-flight spectrum is obtained in the data processor (12). If different kinds of ions having the same m/z value exit, these ions form a single peak in the first time-of-flight spectrum, while these ions appear as separate peaks in the second time-of-flight spectrum even though they have the same m/z value. This is because, in the second mass analysis, the ions collide with the gas and have different times of flight depending on their difference in size.
