ADSORBENT AND METHOD FOR PRODUCING SAME |
摘要 |
<p>An adsorbent that enables solid phase extraction with high efficiency and good selectivity of solutes having a broad chromatographic polarity range including high-polarity solute molecules while suppressing adsorption of impurities, and a solid phase extraction method therefor are provided. A heterocyclic-ring-containing copolymer adsorbent that is provided herein comprises a copolymer that comprises: a multifunctional heterocyclic-ring-containing monomer having a heterocyclic ring containing at least two heteroatoms in the ring system; and a monomer that is copolymerizable with the multifunctional heterocyclic-ring-containing monomer, wherein the multifunctional heterocyclic ring constitutes the main chain structure. Furthermore, the solid phase extraction method comprises a step of bringing a solution containing any one of a low-polarity solute molecule, a moderate-polarity solute molecule, and a high-polarity solute molecule as a solute into contact with the heterocyclic-ring-containing copolymer adsorbent, so that one or more types of solute are selectively adsorbed and held.</p> |
