Applicant's present invention comprises an apparatus having a tandem configuration of a three-dimensional or linear RF multipole ion trap, a linear RF multipole device and a time-of-flight mass spectrometer, and the associated method of operation generating an associated product ion mass spectrum and a mass spectrum of residual parent ions wherein the associated product ion mass spectrum is combined with the mass spectrum of the residual parent ions to generate a three-dimensional mass spectrum of parent and associated product ions from a single, stored population of heterogeneous ions.
