The facility avails itself of two modern mass spectrometers: a Voyager-DE STR MALDI-ToF (Applied Biosystems) and an LTQ XL electrospray-linear ion trap (Thermo) equipped with Electron Transfer Dissociation (ETD). ETD technology carries out a special kind of fragmentation through particular ion-ion reactions obtained by injecting fluoranthene into the collision chamber.
