Abstract
In mass spectrometric analysis equipment, highly charged analyte fragment ions are obtained by electron transfer dissociation of highly charged analyte ions by radical anions and the dissociation products are then deprotonated with non-radical anions. Both the radical anions for electron transfer dissociation and the non-radical anions for deprotonation are produced in a single ion source from a single substance, or a single mixture of substances by adjusting the electrical operating parameters of the ion source.
