The world of Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometry has witnessed, especially in the last 30 years significant advances in many fields of science, such as electronics, magnets, new ICR cell designs, developed ICR event s

Rationale Peak picking algorithms in mass spectrometry face the challenge of picking the correct signals from a mass spectrum. In some cases signal wiggles (side lobes) are also chosen in the produced mass list as if they were real signals. Constrain

In this review, the technical developments of the Fourier transform ion cyclotron resonance (FT ICR) mass spectrometry as well as the developments of the ICR before the implementation of Fourier transform into this technique are described in historic

Ultra-high resolution mass spectrometers produce large amount of MS and MS/MS spectra, whose interpretations may not be easy even for experts in this field. Noise among other interfering problems (such as chemical background, side lobes, side bands,

Reactions between ions and reactive neutrals in the gas phase at near thermal energy conditions are feasible, provided that means exist to trap ions for a couple of seconds for collisions between ions and reactive neutrals to occur. The ion cyclotron

After characterizing the negative ion chemistry of tris(trifluoromethyl)phosphine in a previous work, new insights about the interpretation of the MS/MS mass spectrum of the phosphide anion (CF 3 ) 2 P − m / z 169 could be revealed and are describe

A set of 14 stacked ring electrodes was studied by the SIMION ion trajectory simulation program under a pressure of 1 Pa with different applied RF frequencies and RF voltage amplitudes when a classical DC gradient of 38 V/cm is applied. Ion–neutral

ICR cells with 2 and 4 mm radius have been characterized. In addition the trapping potential of the 4 mm cells was modified with wire mesh screening electrodes to yield a “particle in a box” potential. It was shown that ions of low m / z can be t
