A method of analyzing mixtures of APIs and excipients using X-ray powder diffraction is described. It uses a simple algorithm based on linear regression in which the pure component phases are fitted to the mixture pattern using linear least squares. Unlike many methods that use only the peaks in the

Abstract
A new method for quantitative Xβray phase analysis is described. This universal procedure allows to analyse mixtures of components some of which are not known or partly known substances.
Es wird ein neues Verfahren der quantitativen rΓΆtgenographischen Phasenanalyse beschrieben. Dieses universelle Verfahren ermΓΆglicht, Gemische von Komponenten, die unbekannt oder teilweise unbekannt sind, zu analysieren.
