Abstract
In an embodiment, a collision cell comprises rods each having a first end and a second end remote from the first end; an inductor connected between adjacent pairs of rods; and means for applying a radio frequency (RF) voltage between adjacent pairs of rods. The RF voltage creates a multipole field in a region between the rods; and means for applying a direct current (DC) voltage drop along a length of each of the rods.
