Nachweis von Fragment‐Genesen im Massenspektrometer. 5. Mitteilung Aminosäure‐Sequenzanalyse: Vergleich der DADI/MIKE‐, ‘linked scan’‐ und Kollisionsaktivierungs‐Spektrometrie an aliphatischen Aminosäuren

Abstract: The amino acid sequence in tripeptides and tetrapeptides has been analyzed by DADUMIKE and B/E-'linked stun ' spectrometry, as well as by collisional activation in the first and second field free region of a mass spectrometer embodying the inverse Nier-Johnson geometry. Collisional activation enhances the intensity of fragment ions. Einleitung. -Schon seit langerer Zeit wird die Massenspektrometrie in der Peptidanalytik eingesetzt. Die Aminosauresequenz von Oligopeptiden lasst sich damit an kleinen Substanzmen… Show more

“…From these, sequence information can readily be deduced but will not be elaborated upon here, since this is self-evident from the tables. Furthermore, the daughter ions from unimolecular decomposition of [ + H]+ ions are similar to those reported by others (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16) for collisionally induced decompositions. Instead, some other noteworthy features of the daughter ion spectra are now discussed.…”
