Abstract

See full text

A mass spectrometry apparatus includes a holding table that holds a specimen to be ionized, a probe that identifies a portion of the specimen to be ionized, an ion extraction electrode that extracts ions obtained by ionizing the specimen, a liquid supplying unit that supplies liquid to between the specimen and the probe to form a liquid bridge between the specimen and the probe, a vibrating unit that vibrates one of the probe and the holding table, an electric field generating unit that generates an electric field between the probe and the ion extraction electrode, a mass spectrometry unit that mass analyzes ions extracted by the ion extraction electrode, and a synchronization unit configured to synchronize a time at which ions are generated from the portion with a time at which the mass spectrometry unit measures the ions.
