Zusammenfassung:	A system for analyzing a sample includes a chromatographic device, a mass resolving device, and a data processor. The chromatographic device is configured to separate components of the sample using a chromatographic column. The mass resolving device is configured to characterize mass spectrographic properties of the separated components in an intact state, and fragment the separated components and characterize mass spectrographic properties of the resulting fragments. The data processor is configured to average chromatographic and mass spectrographic properties from a plurality of mass chromatographic data sets, generate an inclusion list identifying components for fragmentation, instruct the chromatographic device to repeat the separation of the sample and instruct the mass resolving device to fragment the components and characterize the mass spectrographic properties of the fragments, and identify at least one component based on the mass spectrographic properties of the intact state and the corresponding fragments.
