    摘要: Systems and methods are used to store an electronic record of all product ion spectra of all detectable compounds of a sample. A plurality of product ion scans are performed on a tandem mass spectrometer one or more times in a single sample analysis across a mass range using a plurality of mass selection windows. All sample product ion spectra of all detectable compounds for each mass selection window are produced. All sample product ion spectra for each mass selection window are received from the tandem mass spectrometer using a processor. All sample product ion spectra for each mass selection window are stored as an electronic record of all detectable compounds of the sample using the processor. The electronic record is used to characterize compounds known at the time the electronic record is stored or to characterize compounds that became known after the electronic record was stored.

    摘要: Systems and methods are disclosed for quantitating detectable compounds of a sample. Sample product ion spectra are received for each mass selection window for each time step. The received sample product ion spectra are searched for the presence of known compounds of interest with known product ion spectra by retrieving the known product ion spectra from a library, retrieving the sample product ion spectra corresponding to the precursor mass selection window expected to contain a precursor ion corresponding to the known product ion spectra, generating product ion traces in time for the sample product ion spectra for the known product ion spectra, calculating a score for the product ion traces and product ion spectra that represents how well known product ions and sample product ions match, and calculating a quantitative value for the known compound from the product ion traces when the score exceeds a threshold value.
