PROBLEM TO BE SOLVED: To provide a method and an apparatus, for an ion adhesion mass spectrometry, wherein, even when metal ions in which an isotope exists are used as ions for adhesion, a precise isotope addition ratio can be obtained and the component and the concentration of a gas to be detected can be measured precisely. SOLUTION: In the method for the ion adhesion mass spectrometry, data on a signal strength corresponding to a mass number obtained by analyzing the mass of the gas, to be detected, to which positively charged metal ions are stuck is processed. By using data on the isotope addition ratio of the metal ions, a correction calculation processing operation is performed. The ion adhesion mass spectrometer which executes the method is composed of an emitter 11, a reaction region 12, a mass spectrograph 13, a mass-spectrometry control part 14, a data processor 15, a cylinder 16 for the gas to be detected, a cylinder 17 for N2 gas for cooling, a cylinder 18 for Ar gas for cooling, a cylinder 19 for H2 gas for cooling and a cylinder 20 for a gas for correction calculation.
