Abstract

The combination of cluster SIMS with an orthogonal time of flight (TOF) mass spectrometer was used for peptide structural analysis. Cluster SIMS were compared with MALDI for imaging biosurfaces. Beside the a, b, c and x, y, z fragments, cluster SIMS generated more internal fragments than MALDI. The technique was also found to be simpler for the analysis of cyclic peptides which required post source decay (PSD) MALDI. It was also useful for molecules which could not be desorbed as metastable ions or could not be enzymatically digested.
