Description

Solid phase extraction (SPE) is a technique commonly used in laboratories to isolate analytes of interest from complex matrices.

Retention Mechanism: Reversed-phaseSample Matrix Compatibility: Aqueous or methanolic solutions. Polyamide Resin: Particle Size: 50-160 mum, 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.
