[0002] A column-based solid-phase extraction (SPE) instrument combines two physical extraction processes: liquid and solid phases. In SPE, the solid phase has a stronger adsorption capacity for the isolate than the solvent in which it is dissolved. As the sample solution passes through the adsorbent bed, the isolate concentrates on its surface, while other sample components pass through the bed. By using an adsorbent that only adsorbs the isolate and not other sample components, a highly pure and concentrated isolate can be obtained.
