Beschreibung

Allgemeine Beschreibung

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

• Polyamide Resin: Particle Size: 50-160 μm, Surf pH: 4.5-7.5, Density: 0.2-0.3 cm³/g, Water Content: < 5 %
• Useful for extracting gylcans from aqueous solutions.
• 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
• Also may be used for the extraction of tannins, chlorophyll, humic acid, pharmacologically active terpenoids, flavanoids, gallic acid, catechol A, protocatechuic acid, phloroglucinol, aromatic carboxylic acids, and nitroaromatic compounds
• Irreversibly retains quinones.
