The separation of ions according to their mass is accomplished with static magnetic fields, time-varying electric fields, or methods that clock the speeds of ions having the same energies—the time-of-flight method.

Static electric fields cannot separate ions by their mass but do separate them by their energy and so provide an important design element by functioning as an energy filter.
