Analysis device and analysis method

An analysis method for generating an intensity distribution spectrum by emitting a primary electromagnetic wave or a primary ray to an analyte and performing component analysis of the analyte based on the intensity distribution spectrum using an analysis device including a storage that stores information and a processor, the analysis method comprising:

• a reading step of reading out, by the storage a substance library in which each of types of substances is associated with a characteristic of the substance;
• and
• a processing step of executing, by the processor, processing based on the substance library,
• wherein
• the substance library is configured by storing hierarchical information of
• superclasses each of which represents a general term of the substance and
• subclasses respectively representing types of a plurality of the substances belonging to the superclass, and
• the processing step includes:
• an acquisition step of acquiring the intensity distribution spectrum;
• an extraction step of extracting characteristics included in the analyte as constituent components of the analyte based on the intensity distribution spectrum acquired in the acquisition step;
• an estimation step of estimating the type of the substance from the subclasses based on the characteristic extracted in the extraction step and the substance library read out in the reading step;
• and
• a display step of causing a display to display the type of the substance estimated from the subclasses in the estimation step and the superclass to which the type of the substances belongs in a hierarchical manner.
