Abstract

The basis for mass analysis by Fourier transform ion cyclotron resonance (FT-ICR) is the motion of ions in a homogeneous magnetic field. Electric fields are used In FT-ICR to modify ion motion (i.e., trapping and excitation fields). Ion interaction with inhomogeneous radio frequency and direct current (dc) electric fields complicates the ion motion and leads to loss of both resolution and sensitivity Modifying the geometry of the FT-ICR cell to produce uniform ion acceleration and homogeneous dc trapping fields resuits in simplified frequency measurements and studies of ion-molecule reactions. © 1990, American Chemical Society.
