  • LC/MS/MS analysis for meat speciation in raw and processed meat product
    Patent number: 11573219
    Abstract: Apparatus, methods and kits for detecting the contamination of a meat sample with another type of meat using parent-daughter ion transition monitoring that identifies peptides specific to a particular type of meat. The meat types detected can include pork, beef, lamb, chicken, duck and/or horse and one or more combinations thereof.

  • Species detection using mass spectrometry
    Patent number: 9373486
    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.
