Abstract

The different calculation method of regression analysis (DCR) can carry out the determination of each compound correctly without the sample with three or more kinds of compounds mixed also carrying out the separation operation. The DCR calculates the value of the coefficient of heavy regression so that the sum of squares of the difference of the predicted value of the measured value of the unknown sample calculated from the measured value of a known sample and the measured value of an unknown sample and the measured value of an unknown sample may become the minimum. This time, DCR analysis is used to determine the mixing ratio of the forged coin of 500 in which 4 kinds of compounds are mixed. The measured data of X-ray Fluorescence Analysis (XRF) was used for the analysis of the forged coin of 500 yen.
