PROBLEM TO BE SOLVED: To provide an analytical curve creation method capable of solving problems of labor in measuring a large number of standard solid samples or difficulty of acquiring standard solid samples.;SOLUTION: An analytical curve creation method includes: a database creation step of creating a database in which a plurality of reference analytical curves are registered; a reference analytical curve storage step of allowing an emission analyzer to store reference analytical curves; an intensity acquisition step of measuring at least one standard solid sample, which contains a measurement target element in a base material with known concentration, by the emission analyzer, and acquiring the intensity of each spectrum of a few types; a correction coefficient calculation step of calculating a correction coefficient which is a detection sensitivity difference between a photodetector of a reference emission analyzer and a photodetector of the emission analyzer; and a correction analytical curve storage step of correcting the stored reference analytical curves by a correction coefficient and allowing the emission analyzer to store the analytical curves.;COPYRIGHT: (C)2012,JPO&INPIT
