Quantitative analysis of a poorly crystalline pharmaceutical mixture, processing PXRD data in reciprocal and direct space. Least-square fits in (a) reciprocal and (c) direct space for sample number 8, are shown, with observed and calculated profiles shown in black and red, respectively. Estimated weight fractions of Eudragit L100 (black, Ph 1) and MCC (red, Ph 2) determined in (b) reciprocal and (d) direct space, and (e) obtained as the mean value between the two spaces. Error bars indicate fitting errors in (b) and (d), and propagated errors in (e). The sum of the weight fractions for each sample (in green) and the values of the Kullback–Leibner distance (AKLD) are reported.
