ABSTRACT:
Desired components can be simply and economically separated and recovered from a sample solution having a complicated composition through a liquid chromatography by passing the sample solution through a separation column, thereby separating components contained therein in the separation column, then selectively passing the eluate from the separation column through a trapping column according to a desired component, thereby trapping the desired component in the trapping column, while discarding or recycling the effluent eluate from the trapping column, and then passing another eluting solution composed of a volatile substance when dried under reduced pressure through the trapping column, thereby recovering eluate containing the desired component from the trapping column.
