Abstract:
1. A method of manufacturing target substances by, with use of a supercritical fluid chromatography apparatus, separating the target substances from a sample injected into a mobile phase containing a supercritical fluid and a solvent, the method comprising the steps of: injecting the sample into the mobile phase; changing a composition of the mobile phase after injecting the sample into the mobile phase; and returning the composition of the mobile phase to a pre-change state after changing the composition of the mobile phase, wherein the step of changing the composition of the mobile phase and the step of returning the composition of the mobile phase to the pre-change state are performed during a period of time from detection of a peak of one of the target substances which is eluted latest from a column among the target substances separated by the supercritical fluid chromatography apparatus to injection of the next sample.
