ABSTRACT:
A method of trapping ions using a quadrupole ion trap device includes applying quadrupole excitation to trapped precursor ions causing them to be driven into the ring electrode where they undergo surface induced dissociation. The resultant product ions are then trapped within the ion trap device.
