PuroSorbTM polymeric adsorbents (PAD) are synthetic, highly cross-linked polymers with a highly porous structure as part of their matrix. With either non-polar or hydrophobic tendencies, they readily adsorb highly soluble organic compounds.
They have a strong affinity for hydrophobic molecules such as polyphenols, vanilla (natural flavor) and naringin (citrus flavanone) that have high electronic density (i.e. unsaturated ring such as benzene). The resin attracts the aromatic groups of the molecules.
The full PAD range is highly stable in acidic or alkaline solutions, as well as the majority of commonly-used organic solvents. They can also be regenerated under mild conditions for prolonged life.
