Abstract
The product ion mass spectra of protonated and cationated peptides of relative molecular mass (RMM) 555-574 Da have been obtained by surface-induced dissociation of MH+ and [M + Cat]+ ions in a four-sector tandem mass spectrometer equipped with a specially designed collision cell. A linked scan of the electric and magnetic sector field strengths of the second mass spectrometer was used to transmit the fragment ions arising from collisions with a stainless steel surface. The resulting mass spectra contained broad metastable ion peaks produced by the dissociation of MH+ and [M + Cat]+ ions before the second magnetic sector, in the fourth field-free region of the instrument.
