摘要:
A method of detecting polymorphs using X-ray produced by a synchrotron source is described. In particular, the method allows to detect particular polymorphs present in small amounts in mixtures of polymorphic compounds present in a prevailing amount. The method offers a powerful resolution of mixtures of polymorph and finds application particularly in the pharmaceutical field.
