A device that permits the ejection of ions with a [[m/z|m/z ratio]] less 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 ions in a circular path. The choice of these voltages determines the [[m/z Ratio]] below which ions are ejected. Unlike the [[Ion Cyclotron Resonance Spectrometer]] no magnetic field is required for the operation of the ion trap.

A device that permits the ejection of ions with a m/z ratio less 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 ions in a circular path. The choice of these voltages determines the m/z ratio below which ions are ejected. Unlike the Ion Cyclotron Resonance Spectrometer no magnetic field is required for the operation of the ion trap.
