Mass spectrometric system

A mass spectrometric system, comprising:

• a mass spectrometric unit that measures a specimen and outputs a mass spectrum;
• and
• an estimator that has an estimation rule on content information, the estimation rule being assigned to each component of a plurality of components that may be contained in the specimen and each measurement time of a plurality of measurement times, each of which is a time elapsed from a start of a measurement of the specimen,
• wherein
• the estimator estimates, based on a mass spectrum output from the mass spectrometric unit, content information on each component in accordance with the estimation rule,
• the estimation rule is defined as

• where
• t is a measurement time,
• i is a component,
• a is a measurement operation,
• res (t, i, a) is the content information indicating an existence determination result,
• j is an index corresponding to a marker such that the magnitude of a peak is stored at the intensity of the marker,
• L is the number of markers,
• I_j is the intensity of the marker j corresponding to the magnitude of a peak,
• g—1, . . . , g_L are a marker coefficient set,
• r—1, . . . , r_L are m/z of a reference material set, where m is mass and z is charge number,
• I_r—1, . . . , I_r_L are intensities of m/z of the reference material, and
• TH (t, i, a) is a threshold, and
• an output of the estimator is the content information including a logical value indicating whether a concentration of a target component exceeds a threshold concentration or not.
