  • METHOD AND SYSTEM FOR INDENTIFICATION OF MICROORGANISMS
    Publication number: 20110224104
    Abstract: A method and system for identification of microorganisms in a sample. The method includes processing the sample to produce at least one group of biomarker molecules from at least one microorganism in the sample, tandem mass-analyzing biomarker fragment ions from the at least one group of biomarker molecules to obtain a sample biomarker tandem mass spectrum of the biomarker, and identifying the microorganism in the sample based on a comparison of the sample biomarker tandem mass spectrum to an experimentally-derived reference tandem mass spectrum (stored in the reference library) from a known microorganism. The system includes a sample processing unit configured to process the sample and produce at least one group of biomarker molecules from at least one microorganism in the sample. The system includes a mass-analyzer for tandem mass analysis biomarker fragment ions.

  • Method and apparatus for processing of biological samples for mass spectrometry analysis
    Patent number: 7858392
    Abstract: A system and corresponding method for processing of biological samples prior to spectroscopy analysis. The system includes a support for an organic sample, a solution applicator configured to apply a solution for extraction of at least one biomarker protein from the organic sample. The system includes a digester-medium applicator configured to apply to the organic sample a digesting medium capable of at least partial digestion of the biomarker proteins into peptides. The system includes a heating device configured to heat at least one of the organic sample, the solution, the digesting medium, and the biomarker proteins to a temperature above room temperature.
