Ten samples of powder mixtures containing known quantities of methamphetamine・HCL and ephedrine・HCl were measured by X-ray diffraction. The respective I/I_O values of 19 peales were selected for calibration. The data was used for the multivariate analyses including a cluster analysis, and a cluster analysis derived from the deviation and a principal component analysis. Subsequently the approximate values of the methamphetamine・HCl contents of unknown samples were determined from the 12×19 matrix. The accurate methamphetamine・HCl contents of unknown samples were calculated from the principal component score. Differences between the theoretical and calculated values of 10 samples ranged from -1.4 to 1.7% (the respective methamphetamine・HCl contents are 3.9,14.5,20.2,34.4,44.0,49.8,60.0,75.2,96.1 and 99.1%).
