A quantitative analysis method and quantitative analysis device speeding detection and resistant to the effect of the condition of the device (fluctuations in sensitivity) in mass spectrometry using a mass spectrometer, i.e., a quantitative analysis method of a measured object using a mass spectrometer, which quantitative analysis method comprising a gas introduction step of mixing a gas of the measured object and a carrier gas different from the gas of the measured object and having two or more natural isotopes and introducing them to a mass spectrometer, a mass spectrometry step of mass spectrometry of the gas of the measured object and the two or more natural isotopes in the carrier gas at the mass spectrometer, and a gas concentration calculation step of calculating a concentration of the gas of the measured object using analyzed values of the two or more isotopes of the carrier gas obtained by the mass spectrometry step as calibration standards.
