Document Type and Number:
WIPO Patent Application WO/2021/059600
Kind Code:
A1
Abstract:
This ion trap mass spectrometer comprises: an ion trap provided with a first electrode and a second electrode that is different from the first electrode; a first voltage control unit that applies, to the first electrode, direct voltage of a plurality of different values by periodically switching thereof; and a second voltage control unit that applies a sinusoidal voltage to the second electrode when an ion trapped by the ion trap is disassociated.
