Abstract
Method and device for rapid characterization of arrays of crystalline, polycrystalline or amorphous materials; in particular for the formation and X-ray diffraction analysis of polymorph libraries and the discovery of new crystal forms. According to one aspect, a multi-well plate comprising a masking plate with an array of openings and a removable base plate is used to crystallize precipitates. X-ray diffraction analysis is performed by scanning an X-ray beam over the base plate and recording diffractograms of the crystalline precipitates.
