Title:
MASS SPECTROMETRY DEVICE AND WAVE DETECTION UNIT
Document Type and Number:
WIPO Patent Application WO/2023/067658
Kind Code:
A1
Abstract:
This mass spectrometry device comprises a mass filter, a wave detection unit, and a power source device. The mass filter selects ions having a mass-to-charge ratio that corresponds to an applied AC voltage. The wave detection unit detects the AC voltage that is applied to the mass filter. The power source device applies an AC voltage to the mass filter on the basis of the AC voltage that was detected by the wave detection unit. The wave detection unit has a plurality of rectifying sections. Each of the plurality of rectifying sections includes a rectifying element. The plurality of rectifying sections are electrically connected to one another in parallel.
