Abstract
A linear ion trap includes a quadrupole having four substantially parallel conductive rods that are substantially coextensive in the axial direction. The rods include two diagonally arranged pairs including one continuous, rod pair and one pair of rods that are segmented such that the two segments in a rod are capacitively coupled to facilitate an RF drop when an RF signal is applied to one longer segment and capacitively provided to the other shorter segment. An RF signal is provided to the continuous rods and tire longer segment of the segmented rods.
