 Elution
            The target compound fraction is repeatedly injected into the trap column, enriched by trapping, and eluted by an organic solvent.
            This enables recovery with a smaller volume of liquid, so subsequent powderization can be performed in a shorter time. In this
            way, the same volume of powdered sample can be puri ed in a shorter time versus elution in reverse phase conditions.
