In SDM (Spectral Determination Method), when there is a large difference in the concentration level between nuclides in the measurement sample, it is expected that the accuracy of quantification of low-concentration nuclides will be poor. In this presentation, we report about investigation of chemical separation scheme for improving accuracy of SDM.
