Multipole assembly configurations for reduced capacitive coupling

A multipole assembly configured for use in a mass spectrometer, the multipole assembly comprising:

• a first plurality of rod electrodes arranged about an axis and configured to confine ions radially about the axis,
• wherein
• the mass spectrometer includes another multipole assembly comprising a second plurality of rod electrodes arranged about the axis and configured to confine the ions radially about the axis, and
• when the multipole assembly is disposed adjacent to the another multipole assembly in the mass spectrometer, an orientation of the first multipole assembly about the axis is rotationally offset relative to an orientation of the another multipole assembly about the axis.

A method comprising:

• disposing a first multipole assembly in a mass spectrometer, the first multipole assembly comprising a first plurality of rod electrodes arranged about an axis and configured to confine ions radially about the axis;
• and
• disposing a second multipole assembly in the mass spectrometer adjacent to the first multipole assembly, the second multipole assembly comprising a second plurality of rod electrodes arranged about the axis and configured to confine the ions radially about the axis,
• wherein the second multipole assembly is disposed in the mass spectrometer such that an orientation of the second multipole assembly about the axis is rotationally offset relative to an orientation of the first multipole assembly about the axis.
