Title:
MASS SPECTROSCOPY DEVICE, IONIZATION DEVICE, AND IONIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/042369
Kind Code:
A1
Abstract:
Provided is a mass spectroscopy device 1 comprising: a probe 111 which sprays a liquid sample; an electrical discharge electrode 112 which is disposed at a position where the liquid sample is sprayed from the probe 111; an electrical discharge electrode attachment part 115 to which is provided a conductive part 116 that is conductive with the electrical discharge electrode, and to which the electrical discharge electrode is detachably attached; a voltage application unit 2, 43 which applies, to the conductive part 116, a voltage for causing the electrical discharge electrode 112 to generate a corona discharge; a current measurement unit 2, 44 which measures a current value flowing through the conductive part while the voltage is being applied; a determination unit 45 which determines that the electrical discharge electrode 112 is attached if the current value exceeds a predetermined threshold; and an output unit 46 which outputs a result of the determination by the determination unit 45.
