The grazing incidence surface-induced dissociation (GI-SID) of various protonated peptides with typical kinetic energies of 350 eV was investigated. Peptide ions were generated by matrix-assisted laser desorption/ ionization (MALDI) using delayed extraction. The collision target surfaces used were a
We report here surface-induced dissociation spectra of three multiply charged peptides: doubly protonated angiotensin I, doubly protonated renin substrate, and triply protonated melittin. For comparison, the collision-activated dissociation spectra of renin substrate and melittin are also presented.
