Claim:
An analytic method for determining crystallographic phases of a measuring sample, the method comprising the steps of: (a) acquiring an X-ray diffraction intensity pattern of the measuring sample and qualitatively phase analyzing the sample using the measured diffraction pattern intensities; (b) acquiring an element X-ray spectrum of the measuring sample and determining measured concentration of chemical elements in the measuring sample from the acquired element spectrum; (c) calculating an X-ray diffraction intensity pattern of the measuring sample; (d) calculating an X-ray element concentration spectrum of the measuring sample; and (e) quantitatively phase analyzing the measuring sample using measured intensities of the acquired diffraction pattern thereby taking into consideration the element concentrations determined in step (b) by simultaneously and iteratively minimizing differences between the calculated and the measured X-ray diffraction intensity patterns and between the calculated and the measured X-ray element concentration spectra.
