    摘要： A refining method according to the present invention is a refining method for crystallizing a compound with at least one crystal form, including setting, as a target wavelength and a target concentration, a specific infrared wavelength and a specific concentration at which a specific crystal form precipitates from a solution of the compound dissolved in a solvent, and using an infrared radiation apparatus capable of emitting infrared radiation including the target wavelength to evaporate the solvent and precipitate the specific crystal form while irradiating a solution of the compound dissolved in the solvent at the target concentration with infrared radiation including the target wavelength.

    摘要： A refining method according to the present invention is a refining method for crystallizing a compound with at least one crystal form, including: setting, as a target wavelength, a specific infrared wavelength at which a specific crystal form precipitates from a solution of the compound dissolved in a solvent; and using an infrared radiation apparatus capable of emitting infrared radiation including the target wavelength to evaporate the solvent and precipitate the specific crystal form while irradiating the solution with infrared radiation including the target wavelength. The specific infrared wavelength is preferably set as the target wavelength based on an infrared absorption spectrum of the crystal form and the dissolution rate of the compound in the solvent.

    摘要： An analysis apparatus includes: an acceptance unit adapted to accept parameters that affect precipitation of a crystal of an analyte; a prediction unit adapted to predict a type of crystal form to be precipitated, based on the accepted parameters; an evaluation unit adapted to evaluate a relationship between the type of crystal form to be precipitated and the parameters, based on a degree of influence that represents an extent to which each of the parameters affects the precipitation of the crystal of the analyte; and a providing unit that provides the type of crystal form to be precipitated and a precipitation condition to a user as information about a crystal form of a crystal to be precipitated. Thus, the type of crystal form to be precipitated and precipitation conditions of each crystal form can be predicted, with regard to an analyte that exhibits crystal polymorphism.
