Abstract
Systems and methods are provided for species detection using mass spectrometry. In various embodiments, a multiple reaction monitoring (MRM) experiment is performed on a sample targeting one or more peptide transitions that are unique to one or more species using a tandem mass spectrometer. One or more measured product ion spectra are received from the tandem mass spectrometer using the processor. The one or more measured product ion spectra are compared to product ions of the one or more peptide transitions that are unique to one or more species using the processor. One or more species of the sample are detected by reporting product ions of the one or more peptide transitions that are unique to one or more species that match the one or more measured product ion spectra using the processor.
