| 发明名称 | Species detection using mass spectrometry | ||
| 摘要 | 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. | ||

| 主权项 | 1. A system for species detection using tandem mass spectrometry, comprising: a tandem mass spectrometer that performs a multiple reaction monitoring (MRM) experiment on a sample targeting one or more peptide transitions that are unique to one or more species; and a processor in communication with the tandem mass spectrometer that receives one or more measured product ion spectra from the tandem mass spectrometer,compares the one or more measured product ion spectra to product ions of the one or more peptide transitions that are unique to one or more species, anddetects one or more species of the sample 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. | ||
