PROBLEM TO BE SOLVED: To provide a quantification method capable of drawing a calibration curve by removing a known amount of an object component, and quantitating a quantification target component in a sample, even when the known amount of the object component cannot be added. SOLUTION: In this quantitative analysis method of a metal sample including a measuring object component comprises processes for: dipping the metal sample in a solvent capable of removing the measuring object component from the metal sample; removing the measuring object component from the dipped metal sample into the solvent; determining the removed amount of the measuring object component; determining each ion amount caused by the measuring object component of the dipped metal sample and an non-dipped metal sample; drawing the calibration curve (X-axis: the removed amount of the measuring object component, Y-axis: the ion amount caused by the measuring object component), and extrapolating the calibration curve to the X-axis. The method has a characteristic wherein the interception between the calibration curve and the X-axis shows the amount of the measuring object component. COPYRIGHT: (C)2006,JPO&NCIPI
