Abstract:
1. A method of mass spectrometry comprising: determining a first physico-chemical property and a second physico-chemical property of components, molecules or analytes in a first sample, wherein said first physico-chemical property comprises mass or mass to charge ratio and said second physico-chemical property comprises elution time, hydrophobicity, hydrophilicity, migration time, or chromatographic retention time; determining a first physico-chemical property and a second physico-chemical property of components, molecules or analytes in a second sample, wherein said first physico-chemical property comprises mass or mass to charge ratio and said second physico-chemical property comprises elution time, hydrophobicity, hydrophilicity, migration time, or chromatographic retention time; and probabilistically associating, clustering or grouping data relating to components, molecules or analytes in said first sample with data relating to components, molecules or analytes in said second sample, wherein the data is obtained by performing processing of the first sample and the second sample the processing including performing mass spectrometry using a mass spectrometer, and the method further including: clustering the data into one or more first clusters of data points; and probabilistically clustering the data points into one or more second clusters of data points.
