Efficient collision-induced dissociation multistage tandem high-resolution mass spectrometry of peptide ions is demonstrated for the first time. Specifically, four-stage Fourier transform ion cyclotron resonance collisioninduced dissociation tandem-in-time MS4 is demonstrated for bradykinin quasimolecularions, MH+, produced by matrix-assisted laser desorption/ionization. We combine off-resonant excitation and ion axialization to improve the efficiency of parent ion dissociation and product ion collection and detection at everyMS stage. We observe successive loss of water/ammonia from the C-terminus to leave an (MHNH3/H20)+ ion in the second stage, followed by successive losses of the next two amino acids, arginine and phenylalanine. High mass resolving power is achieved throughout allfour MS stages, in an experiment that consumes~ 10 pmol of peptide and takes only~ 5 min. We project that it should be possible to automate this experiment for high-speed sequencing of biopoly-
