Ion trajectory calculations have confirmed that space charge interactions can be a source for mass discrimination seen in Fourier transform-ion cyclotron resonance (FT-ICR) spectra. As compared with the previously recognized mechanism of z-axis excitation, ion-ion repulsion is a mechanism which spec

Ion motion during frequency sweep excitation was computer simulated to study the effect of the direction of frequency swee on the z motion of ions in a cylindrical Fourier transform ion cyclotron resonance (T-ICR) cell. It is shown that the z motion is more forcefully excited by upsweep than by down
The cyclotron-resonance model, which has been suggested as an explanation of a purported enhancement of transport of ions through the membranes of cells exposed to weak, lowfrequency-modulated RF fields, is shown to be inconsistent with basic physical principles. Under the conditions of the model,
