The time-of-flight effect in Fourier transform mass spectrometry (FTMS) with an external ion source was quantified. The time-of-flight profiles of ions of different masses were measured by stepping the time interval between the ionization pulse and the gating of the trapping voltage (T gate ). The o

## Abstract High‐performance matrix‐assisted laser desorption/ionization (MALDI) using 7 T Fourier transform mass spectrometry (FTMS) was investigated for peptide amino acid sequence analysis. Two synthetic peptides representative of the type which would be displayed by major histocompatibility com
