Product ions with masses above that of the precursor ion have been observed in high-energy collisions between protonated peptides MH+ with molecular weight ranging from 555 to 2585 and hydrogen-containing target gases (XHn) such as ammonia and methane. A major product ion observed had a mass corresponding to elimination of two hydrogens from the ion/target complex [MH+XHn-2H]+. Incorporation of 14 Da, [CH4-2H], into fragment ions was observed in collision-induced dissociation (CID) of renin substrate with methane as the target gas. Optimum collision energies were shown to depend directly on the mass of the peptide ions and span from 12 to 24 eV in the center-of-mass frame.
