Abstract
Ions are injected into an orbital electrostatic trap. An ejection potential is applied to an ion storage device, to cause ions stored in the ion storage device to be ejected towards the orbital electrostatic trap. Synchronous injection potentials are applied to a central electrode of the orbital electrostatic trap and a deflector electrode associated with the orbital electrostatic trap, to cause the ions ejected from the ion storage device to be captured by the electrostatic trap such that they orbit the central electrode. Application of the ejection potential and application of the synchronous injection potentials are each started at respective different times, the difference in times being selected based on desired values of mass-to-charge ratios of ions to be captured by the orbital electrostatic trap.
