Descripción general

Retention Mechanism: Reversed-phase
Sample Matrix Compatibility: Aqueous or methanolic solutions

  • Polyamide Resin: Particle Size: 50-160μm, Surf pH: 4.5-7.5, Density: 0.2-0.3 cm3/g, Water Content: < 5 %
  • Used to adsorb polar compounds (-OH groups, esp. phenolic compounds) from aqueous or methanolic solutions under the reversed-phase mechanism through strong hydrogen bonding between compound hydroxyl groups and amide groups of the resin
  • Useful for extracting tannins, chlorophyll, humic acid, pharmacologically active terpenoids, flavanoids, gallic acid, catechol A, protocatechuic acid, and phloroglucinol
  • Also useful for extracting aromatic carboxylic acids and nitroaromatic compounds
  • Irreversibly retains quinones
