ABSTRACT:
An apparatus and method for isolation of selected ions of interest in a 2-D ion trap is provided. The 2-D ion trap of the invention has an octopole field which is obtained by modification of the electrodes, modification of the positioning of the electrodes or both. The 2-D ion trap of the invention also includes a means for forcing ion motion in the ion trap in a first and a second direction independently and sequentially.
