Title:
ANALYSIS DEVICE AND ANALYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2023/228657
Kind Code:
A1
Abstract:
An analysis device 10 comprises: a reception unit 11 that receives a parameter that affects the precipitation of crystals from an analysis target; a prediction unit 13 that, on the basis of the received parameter, predicts the type of crystal form that will precipitate; an evaluation unit 14 that, on the basis of a degree of effect that is the degree to which the parameter will affect the precipitation of crystals from the analysis target, evaluates the relationship between the parameter and the type of crystal form that will precipitate; and a provision unit 15 that provides a user with the type of crystal form that will precipitate and precipitation conditions as information relating to the crystal form of crystals that will precipitate. The present invention thereby provides an analysis device and an analysis method that make it possible to, with regard to an analysis target having polymorphic forms, predict the types of crystal forms that will precipitate and the precipitation conditions for each crystal form.
