Multichannel rapid sampling of chromatographic peaks by tandem mass spectrometer

摘要

Systems and methods for optimizing the analysis of co-eluting compounds during a cycle of a tandem mass spectrometer system are provided. The tandem mass spectrometer system switches fast from analyzing one compound ion to analyzing another compound ion and from one collision cell energy to another. The fast switching allows complex sampling patterns that improve coverage of the ionic signal of the co-eluting compounds while allowing different collision cell energies to be analyzed.
