Comparison of collision-induced dissociation and surface-induced dissociation mass spectra of peptides obtained using a four-sector mass spectrometer

The high energy argon CID and 100 eV surface-induced dissociation mass spectra of MH + ions of three peptides of RMM 1300—1850 Da are reported and compared. The fragmentation patterns of these ions are discussed in terms of the nature of the ions produced in each case. The SID mass spectra resemble...

Description
Summary:The high energy argon CID and 100 eV surface-induced dissociation mass spectra of MH + ions of three peptides of RMM 1300—1850 Da are reported and compared. The fragmentation patterns of these ions are discussed in terms of the nature of the ions produced in each case. The SID mass spectra resemble more closely those produced by low rather than high energy CID obtained using hybrid tandem was spectrometers. This observation suggests that, with the device used for these SID experiments, only a small amount of the kinetic energy of the precursor ions is converted to internal energy.
