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.
