Macroporous adsorption resin AB-8/Resin AB-8

CAS No.:
Item No.: I0341
Store at: RT
Grade: BR

Specific surface area: 450 ~ 500m2 / g

Grain diameter range: 0.3 ~ 1.2 mm

Average pore diameter: 12 ~ 16 nm

Wet apparent density: 0.7g/ml

Porosity: 45 ~ 50%

Residual organic matter: ≤ 20ppm

Physicochemical properties:milky white spherical particles, AB-8 is polystyrene non-polar adsorption resin, with a certain ester group on the surface, and the hydrophilicity has been improved, but the adsorption mechanism is still hydrophobic adsorption. The specific surface area and pore diameter of the resin are large, which is suitable for adsorbing various traditional Chinese medicine components with certain hydrophobicity. The adsorption capacity is large, the elution is easy, and the adsorption kinetic performance is good. It is stable to heat, organic solvents and acids and bases under general service conditions, so it has a long service life.

Purpose: biochemical research, it does not adsorb proteins, sugars, inorganic acids, bases, salts and small molecular hydrophilic organic substances, so it can separate general traditional Chinese medicine components from these substances.
