Answer:The resin is a porous, nonionic styrene–divinylbenzene polymeric adsorbent.
Answer:The listed particle-size range is 250–850 µm, with a mean pore size of approximately 260 Å.
Answer:It adsorbs suitable organic compounds onto a hydrophobic polymer matrix and allows their recovery through an appropriate desorption or elution step.
Diaion® HP-20 is a nonionic, porous styrene–divinylbenzene polymeric adsorbent used for chromatographic adsorption and extraction of organic compounds. Its hydrophobic polymer matrix enables retention of suitable molecules from aqueous or mixed-solvent sample streams, followed by solvent-based washing and desorption as appropriate for the method. The resin has a reported particle size of 250–850 µm, mean pore size of approximately 260 Å and surface area around 500 m²/g. It is supplied in a 1,000 g package for laboratory separations and adsorptive purification workflows. HP-20 is a synthetic polymer adsorbent rather than an ion-exchange resin or silica-based stationary phase. Loading capacity, solvent compatibility and elution conditions require method-specific optimization.
