Adsorption technologies have been developed for decades, and adsorption methods commonly used to purify molecules may involve toxic solvents, as well as expensive distillation and precipitation processes. The earliest adsorbent used is activated carbon, which has a large specific surface area and can remove impurities through physical adsorption, chemical adsorption and ion exchange adsorption, but the cost of pyrolysis to regenerate carbon media is high. Safe and economically efficient synthetic resins can extract target molecules more efficiently than solvent precipitation and activated carbon with additional recyclability benefits. Macroporous adsorbent resin is a polymer with porous internal structure, through the principles of adsorption and molecular sieve to concentrate and separate organic substances. Macroporous adsorbent resins have good selectivity to organic matter and are not affected by the presence of inorganic salts, strong ions and low molecular compounds.
Amerigo Scientific offers adsorbent resins for a wide range of applications, including adsorption concentration, separation (of enzymes, amino acids, peptides, etc.), purification (of stevioside, antibiotic, etc.), decolorization (of juice), deodorization, desalination and softening, chemical analysis, and environmental protection.
