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

Detection of Fragment Genesis in the Mass Spectrometer. V. Amino Acid Sequence Analysis by DADI/MIKE, Linked Scan and Collisional Activation Mass Spectrometry. Aliphatic Amino Acids The amino acid sequence in tripeptides and tetrapeptides has been analyzed by DADI/MIKE and B/E-‘linked scan’ 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.
