Peptide fragmentation by keV ion-induced dissociation.
We have studied multiple ionization and dissociation of a trapped protonated peptide (leucine enkephalin) as induced by keV singly and doubly charged ions (H(+), He(+, 2+)) to demonstrate the potential of keV ions as a future tool for peptide identification. In contrast to conventional excitation techniques, the fragmentation pattern exhibits very strong peaks due to loss of sidechains in addit...

متن کاملEmergence of energy dependence in the fragmentation of heterogeneous materials.
The most important characteristics of the fragmentation of heterogeneous solids is that the mass (size) distribution of pieces is described by a power law functional form. The exponent of the distribution displays a high degree of universality depending mainly on the dimensionality and on the brittle-ductile mechanical response of the system. Recently, experiments and computer simulations have ...
متن کاملEnergy dependence of impact fragmentation of long glass rods
We have performed an experimental study of impact fragmentation with a focus on the dependence on the energy input. Long glass rods were dropped horizontally onto the ground from seven di erent heights. We nd that the energy dependence is better characterized by studying the di erential mass distribution rather than the cumulative mass distribution. For lower dropping heights, the di erential m...
متن کاملIon mobility studies of carbohydrates as group I adducts: isomer specific collisional cross section dependence on metal ion radius.
Carbohydrates play numerous critical roles in biological systems. Characterization of oligosaccharide structures is essential to a complete understanding of their functions in biological processes; nevertheless, their structural determination remains challenging in part due to isomerism. Ion mobility spectrometry provides the means to resolve gas phase ions on the basis of their shape-to-charge...
