WIPO Patent Application WO/2019/230001
Kind Code:
A1
Abstract:
The quadrupole mass filter is provided with: four electrodes arranged about the central axis so as to constitute a quadrupole electrode; attachment parts to which multiple electroconductive parts are attached in such a manner that at least one of same is disposed in a direction toward a position between each pair of adjacent electrodes of the four electrodes, as seen from the central axis; and a holding unit having a hollow part and holding the four electrodes and the multiple electroconductive parts. The electroconductive parts are held by the holding unit in a state of being attached to the attachment parts by using the elasticity of the material forming the electroconductive parts.
