Web20 de mai. de 2024 · Common fragmentation techniques such as collision-induced dissociation (CID) and higher energy collisional dissociation (HCD) are limited due to extensive phosphate-related neutral loss. Electron transfer dissociation (ETD) has shown to preserve labile modifications, but is restricted to higher charge states, missing the … WebFigure 6 Basic principle of sensitivity determined by collision-induced dissociation. High-sensitivity compounds form stable adducts with large binding energy, which can survive high-ion-energy conditions in the instrument. Low-sensitivity compounds dissociate at lower energies. The sensitivity can therefore be parameterized by the voltage.
