Abstract
An ion cyclotron resonance cell has at least one trapping electrode comprised of electrically isolated sections that are used for the detection of an induced ion image signal. Such an arrangement increases the sensitivity of image signal detection without a significant increase in the amplitude of parasitic harmonics. When a multielectrode detection arrangement is used, the resolving power of an analyzer incorporating such a cyclotron resonance cell multiplies without a corresponding sensitivity loss.
