Abstract: An analyzer includes a pretreatment device and a mass spectrometer. The pretreatment device includes a solid phase extraction mechanism. The mass spectrometer performs mass spectrometry on a sample pretreated by the pretreatment device and then subjected to ionization. The analyzer also includes a storage unit that stores data on dependence of signal intensities of the analyte substance to be measured and the internal standard upon the concentration of a substance inhibiting ionization in the sample, and that stores data on a recovery rate. The analyzer also includes a correcting unit that corrects measurement results of the sample and the internal standard on the basis of the data stored in the storage unit.

Abstract: There is a tendency of the intensity and the shape of a spectrum to be measured transitioning with the passage of measured time, depending on the volatility and the reactivity of a component. A mass spectrometric system includes: 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 and each measurement time. The estimator estimates, based on a mass spectrum output from the mass spectrometric unit, content information on each component of a plurality of components that may be contained in the specimen in accordance with the estimation rule.
