Product Overview

• Strong alkalinity and high selectivity: Type I quaternary ammonium salt with strong affinity for high-valence anions (such as SO₄²⁻, PO₄³⁻), and stable exchange over a wide pH range.

• Gel structure: Uniform pore size, suitable for the separation of small molecule anions (organic acids, halogens, nucleotides), with high chromatographic resolution.

• Good chemical stability: Resistant to acids, alkalis, and organic solvents; high mechanical strength; regenerable and recyclable.

• Food-grade compliance: Complies with FDA 21 CFR 173.25, suitable for food and pharmaceutical processing.

• Ion exchange chromatography: Separation and purification of amino acids, sugars (boronic acid complexes), nucleotides, antibiotics, and organic acids.

• Water treatment: Preparation of pure/ultrapure water, removal of anions (Cl⁻, NO₃⁻, SO₄²⁻), decolorization and impurity removal.

• Food industry: Decolorization and desalination of sugar solutions.

• Removal of anionic impurities and pigments from wine/juice.

• Biopharmaceuticals: Fermentation broth impurity removal, bioproduct desalination, removal of pyrogens and anionic contaminants.

• Chemical refining: Organic solvent decolorization, removal of acid radicals, catalyst recovery.
