Quantitative analysis method and quantitative analysis apparatus

A quantitative analysis method of quantifying a target compound contained in a sample derived from an organism, the quantitative analysis method comprising:

• a category selection step of receiving selection by a user of one category including a target sample from among a plurality of categories determined in advance for the sample;
• a preprocessing step of performing a predetermined preprocessing including derivatization on the target sample;
• a measurement execution step of executing gas chromatograph mass spectrometry on a preprocessed target sample preprocessed by the preprocessing step based on analysis condition information provided from a database storing the analysis condition information for the gas chromatograph mass spectrometry and calibration curve information for quantification by a standard addition method for each of the plurality of categories;
• and
• a quantitative processing step of performing quantitative processing based on data obtained in the measurement execution step using the calibration curve information corresponding to the category selected in the category selection step, the calibration curve information being provided by the database.
