System and method for analyzing contents of sample based on quality of mass spectra |
摘要 |
A method of performing tandem mass spectrometry (MS/MS) for identifying contents of a sample includes performing a mass spectrometry (MS) scan of the sample to obtain an MS/MS mass spectrum; identifying a first precursor ion species in the MS mass spectrum; performing an initial MS/MS scan of the first precursor ion species to obtain an initial MS/MS mass spectrum; and determining whether the initial MS/MS mass spectrum has a quality acceptable for peptide sequencing. When the first MS/MS mass spectrum has an unacceptable quality, the method further includes performing a subsequent MS/MS scan of the first precursor ion species to obtain a corresponding subsequent MS/MS mass spectrum of the first precursor ion species, and determining whether the subsequent MS/MS mass spectrum has a quality acceptable for peptide sequencing.
