Ionization device, mass spectrometry apparatus, mass spectrometry method, and imaging system

摘要

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.

1. An ionization device comprising:
a holding table configured to hold a specimen to be ionized; a probe configured to identify a portion of the specimen to be ionized; an ion extraction electrode configured to extract ions obtained by ionizing the specimen; a liquid supplying unit configured to supply liquid to between the specimen and the probe to form a liquid bridge between the specimen and the probe; a vibrating unit configured to vibrate one of the probe and the holding table; an electric field generating unit configured to generate an electric field between the probe and the ion extraction electrode; and a synchronization unit configured to perform at least one of the following two synchronization processes on the basis of vibration of one of the probe and the holding table: (i) synchronizing a time at which ions are generated from the portion with a time at which a mass spectrometry unit for mass analyzing the ions extracted by the ion extraction electrode measures the ions, and (ii) synchronizing vibration of the probe with vibration of the holding table.
