Abstract:
A method of screening for a new crystal form of a substance, which comprisessolidifying the substance in one or more capillary spaces each independently having an inside diameter from about 0.1 mm to about 5 mm to produce at least one crystal form of the substance; analyzing the crystal form of the substance in at least one of the capillary spaces while the substance remains in the capillary space, using at least one technique chosen from microscopic analysis, thermal analysis, diffraction analysis, and spectroscopic analysis; and classifying the crystal form by comparing the analytical results of the crystal form of the substance to those of a know crystal form or forms of the substance and determining if the crystal form of the substance produced is new.
