  • Patent number: 10928363
    Abstract: At least one stable isotope reagent is added to each biological sample and standard sample to prepare biological samples for analysis and standard sample for analysis. The quality of the biological samples is evaluated using data of one set of biological samples for analysis composed of a plurality of biological samples for analysis. Besides, the quality of a pretreatment and/or analysis of each set of samples for analysis is evaluated using data obtained by analyzing the standard sample for analysis before and after an analysis of one set of samples for analysis. An abnormality in a chromatograph or mass analyzer used for the analysis of one set of samples is evaluated by the data obtained by analyzing a sample for device evaluation before and after the analysis of one set of samples for analysis. Thus, the quality of data obtained by chromatographic mass spectrometry on biological samples is comprehensively evaluated.
