Combined Spectroscopic Method for Rapid Differentiation of Biological Samples

摘要

A method for differentiating complex biological samples, each sample having one or more metabolite species. The method comprises producing a mass spectrum by subjecting the sample to a mass spectrometry analysis, the mass spectrum containing individual spectral peaks representative of the one or more metabolite species contained within the sample; subjecting the individual spectral peaks of the mass spectrum to a statistical pattern recognition analysis; identifying the one or more metabolite species contained within the sample by analyzing the individual spectral peaks of the mass spectrum; and assigning the sample into a defined sample class.
