摘要： A mass spectrometer comprising a collision, fragmentation or reaction cell (4) is disclosed. The collision, fragmentation or reaction cell (4) is repeatedly switched back and forth between a high fragmentation mode of operation and a low fragmentation mode of operation. Mass spectral data sets are obtained in both modes of operation. A decimal mass filter is applied to one or both sets of data. In particular, fragment ions or metabolites related to a parent or precursor ion of interest are identified on the basis of having a decimal mass which is similar to that of the parent or precursor ion of interest.

摘要： A method of rapidly analyzing unexpected metabolites in a metabolite analyzing system is disclosed. A control sample is run and analyzed to generate an exclusion list of unwanted sample components. A single analyte sample is then run and programmatically uses the exclusion list containing the unwanted metabolites to dynamically filter out data regarding components present in both the control sample and the analyte sample. The remaining components in the analyte sample are analyzed for unexpected metabolites of interest. The present invention allows for the analysis to be automated and eliminates the need for a second analyte sample run for the purpose of eliminating common components in the samples.
