Abstract:
1. A system for analyzing analytes in a sample, comprising: (a) an ion source for emitting ions from the sample; (b) a mass spectrometer adapted to receive the ions from the ion source, wherein the mass spectrometer includes: (c) a controller operatively coupled to the mass spectrometer and configured to control the first mass analyzer to select for a designated ion of interest and to control the second mass analyzer to select for a designated ion fragment of interest; (d) data storage for storing at least one analyte parameter set, wherein each analyte parameter set includes: (e) wherein the controller is responsive to the analyte parameter set, and during the retention time window for each analyte parameter set the controller is configured to control the first mass analyzer to select for the corresponding designated precursor ion and to control the second mass analyzer to select for the corresponding designated ion fragments; (f) wherein the controller is configured to determine a chromatographic trace for a plurality of the designated ion fragments in the analyte parameter set and wherein the controller is configured to determine a combined chromatographic trace corresponding to a non-linear combination of a plurality of the designated ion fragment chromatographic traces.
