Abstract
A traveling wave multipole comprising two or more pairs of segmented electrodes arranged around a central axis; and a voltage supply. The voltage supply configured to supply the segments of each pair of electrodes with a different RF and DC potential; and match RF and DC potentials with a location of an ion of target m/z moving through the traveling wave multipole such that as the ion travels along the multipole the ion experiences the same RF and DC potentials while another ion of a second target m/z concurrently experiences a different RF and DC potentials at another location within the traveling wave multipole.
