Electron Capture Dissociation

Neutralization-reionization mass spectrometry (MS) is of unique value for preparing and characterizing highly reactive and unstable neutral species.



These include the intermediate in the dissociative-recombination reaction H3O+ + e- → H2O + H + 6.4 eV. Following an earlier suggestion, using neutralization accompanying surface-induced dissociation (SID) to form an unstable site did not yield new cleavage reactions in multiply charged protein cations from electrospray ionization (ESI) with Fourier transform (FT) MS.
