摘要： A measuring method for determination of the content of a substance in a specimen on the basis of the value of a physical property measured with the specimen in which the determination is influenced by another substance coexisting with the object substance in the specimen, characterized in that: the value of the physical property measured with the specimen with a known content Ht of the coexisting substance is corrected to a value Vc of the physical property calculated with a standard content value Hts as the content Ht of the coexisting substance on the basis of a correction table showing the relationship between the contents Ht of the coexisting substance and set values V of said physical property for the respective key contents of the object substance. The measuring method permits instantaneous determination with high precision of the content of a substance for which no calibration curve can be prepared because of the effects of a coexisting substance.
