## Abstract We describe the current state of the onβline combination of capillary electrophoresis (CE) electrospray ionization (ESI) Fourier transform ion cyclotron resonance (FTICR) mass spectrometry (MS), and discuss aspects of the FTICR technique relevant to its use as a detection scheme for onβ
The experimental Fourier transform ion cyclotron resonance (FT/ICR) frequency range has been extended to 107 MHz. We report the observation of FT/ICR signals from electron-ionized species of mass-to-charge ratio 8, 7, 6, 5, 4, 3, 2, and 1 ΞΌ per elementary charge. We show that moderately high charge
Two-dimensional Fourier transform (2D FT) spectroscopy is applied to ion cyclotron resonance (ICR) to obtain direct evidence for mass transfer due to ion-molecule collisions. The 2D FI ICR experiment, which is closely analogous to 2D exchange NMR spectroscopy (NOESY), yields similar information to t
