Title (EN) METHOD FOR MEASURING ISOTOPE CONCENTRATION
(FR) PROCÉDÉ DE MESURE DE CONCENTRATION ISOTOPIQUE
(JA) 同位体濃度の測定方法
Abstract: front page image
(EN) A method for measuring the isotope concentration of an element contained in a sample, which comprises subjecting the sample to the isotope dilution and thereafter measuring the intensity of an objective signal; and a kit for use in measuring the isotope concentration of a specific element or the isotope concentration in a specific position in a sample. The above method allows the adjustment of the ratio between the intensity of an objective signal derived from an isotope of an element and that of the objective signal derived from another isotope of said element, which has resulted in the accurate measurement of an isotope concentration.
(FR) La présente invention a trait à un procédé de mesure de la concentration isotopique d'un élément contenu dans un échantillon, comprenant la dilution isotopique de l'échantillon suivie de la mesure de l'intensité d'un signal objectif ; et une trousse destinée à être utilisée dans la mesure de la concentration isotopique d'un élément déterminé ou de la concentration isotopique dans une position déterminée dans un échantillon. Le procédé selon l'invention permet l'ajustement du rapport entre l'intensité d'un signal objectif dérivé d'un isotope d'un élément et celle du signal objectif dérivé d'un autre isotope dudit élément, permettant ainsi la mesure précise d'une concentration isotopique.
