Method for separating odorous compound and supercritical fluid chromatograph

A supercritical fluid chromatograph, comprising:

• an odorous compound database in which measurement data of a plurality of odorous compounds, acquired by a predetermined measurement technique using a supercritical fluid chromatograph, are recorded;
• a column filled with a packing material made of a polymer having an unsaturated hydrocarbon structure;
• a supercritical fluid supply section configured to supply the column with a supercritical fluid of a predetermined substance;
• a sample injection section located in a passage extending from the supercritical fluid supply section to the column, and configured to inject a sample into the supercritical fluid;
• a measurement section configured to sequentially perform a measurement of an effluence from the column by the predetermined measurement technique;
• and
• an odorous compound identification section configured to identify a plurality of odorous compounds contained in the effluence by comparing measurement data acquired by the measurement with the measurement data recorded in the odorous compound database.
