Analysis apparatus and analysis method

An analysis apparatus comprising:

• a processor coupled to a memory, the memory storing instructions, that when executed by the processor, configure the processor to:
• receive parameters that affect precipitation of a crystal of an analyte, the parameters including a structural formula of the analyte,
• predict a first type of crystal form to be precipitated, based on the accepted parameters,
• 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
• provide the predicted 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;
• and
• after precipitating a crystal based on the parameters and the provided precipitation condition;
• compare a form of the precipitated crystal with the predicted first type of crystal form:
• change the contribution ratios based on the comparison;
• and
• predict a second type of crystal form to be precipitated based on the changed contribution ratios.
