QUINONE ANALYSIS METHOD AND ONLINE SFE-SFC SYSTEM FOR IMPLEMENTING SAID METHOD

摘要

This quinone analysis method comprises: a sample sealing step for sealing a sample including quinones in an extraction container; an extraction step for, after the sample sealing step and as a series of extraction operations, carrying out "static extraction" in which a first mobile phase solvent for extracting components including quinones from the sample is supplied from a mobile phase supply unit to the extraction container and the extraction container is left still in a state of being filled with the first mobile phase solvent, and then carrying out "dynamic extraction" in which the first mobile phase solvent including components extracted from the sample is allowed to flow through the analysis column and at least the components including quinones from among the components included in the first mobile phase solvent are captured by the analysis column; and an analysis step for supplying, from the mobile phase supply unit, a second mobile phase solvent for eluting, from the analysis column, the components captured by the analysis column as a result of the series of extraction operations, causing the second mobile phase solvent to flow through the analysis column, separating and eluting the components captured by the analysis column, and detecting the same using a detector.
