✦ Synopsis

Collision

-induced dissociation (CID) can be effected in the interface region between atmospheric pressure ionization sources and single quadrupole mass analyzers. By varying the electric field in these cone-voltage CID experiments energy-resolved mass spectra can be obtained leading to breakdown graphs exploring the energy evolution of the fragmentation pathways. The breakdown graphs obtained from these cone-voltage CID studies are very comparable to those obtained by varying the collision energy in the quadrupole collision cell of a BEqQ mass spectrometer. The comparison has been made for the protonated peptides H-

The microheterogeneity of the paracelsin mixture broth of Trichoderma reesei was analysed using mass spectrometric methods, in particular high-energy collision-induced dissociation (CID) tandem mass spectrometry (MS/MS). Based on the liquid secondary ion mass spectrum of the mixture, there are three
