Abstract:
Acceleration of decelerated ions and a reduction in the velocity dispersion width of decelerated ions are both achieved, whereby the sensitivity of detected ion sensitivity is improved and resolution is improved. The distance dx between at least one set of facing rod-shaped electrodes among rod-shaped electrodes ( 4 - 2 - a ) to ( 4 - 2 - d ) differs at the inlet part at which ions enter and the outlet part at which ions exit, and the distance dx between the at least one set of facing rod-shaped electrodes is gradually reduced or increased from the inlet part toward the outlet part.

Claim (Index 2):
A mass spectrometer, comprising:\n 2n rod-like electrodes; and a control unit configured to apply a DC voltage U and a radio frequency voltage V RF  cos \u03a9t to the rod-like electrodes to generate a high-frequency multipole electric field equal to or more than a quadrupole electric field between the rod-like electrodes, wherein: a distance between at least a pair of facing rod-like electrodes of the rod-like electrodes at an entrance portion that ions enter is different from the distance at an exit portion from which ions are emitted; and the distance between the at least pair of the facing rod-like electrodes is gradually increased from the entrance portion toward the exit portion.
