A device that permits the trapping of ions by means of an alternating current voltage. The ejection of ions with a ''[[m/z]]'' less than a prescribed value and retention of those with higher mass depends on the application of radio frequency voltages between a ring electrode and two end-cap electrodes to confine the ions in a circular path. The choice of these voltages determines the ''[[m/z]]'' below which ions are ejected.
Ion trapping device that permits the ejection of ions with an ''[[m/z]]'' lower than a prescribed value and retention of those with higher mass. It depends on the application of radio frequency voltages between a ring electrode and two end-cap electrodes to confine the ion motion to a cyclic path described by an appropriate form of the Mathieu equation. The choice of these voltages determines the ''[[m/z]]'' below which ions are ejected.
 
The term [[cylindrical ion trap]] is deprecated.
