20080272292System and Method for Grouping Precursor and Fragment Ions Using Selected Ion Chromatograms - LC/MS data generated by an LC/MS system is analyzed to determine groupings of ions associated with originating molecules. Ions arc grouped initially according to retention time, for example, using retention time or chromatographic peaks in mass chromatograms. After initial groupings are determined based on retention time, ion peak shapes are compared to determine whether ions should be excluded. Ions having peak shapes not matching other ions, or alternatively a reference peak shape, are excluded from the group.11-06-2008
20080208485System and Method for Tracking and Quantitating Chemical Entities - In complex separations, more than one entity may have the same molecular weight, to within the ability of an instrument to distinguish. Accurate mass measurements are used in light of the previously unknown regularities in retention time to determine a retention time (N pairs of values (t08-28-2008
