H103 is a type of large-pore adsorption resin, non-polar, mainly developed for adsorbing and separating small molecule organic compounds, belonging to the polystyrene system. Due to the use of a special manufacturing process, the pore size is very uniform and it has a high specific surface area. It is widely used in organic wastewater treatment, removal of organic residues in food, removal of pesticide residues in agricultural products, and removal of organic residues in traditional Chinese medicine, among other applications.
X-5 is a type of broad-spectrum adsorption resin belonging to the polystyrene system, produced through a special process to achieve a structure with uniform pore size and high specific surface area. The pore size is medium, forming a series of large, medium, and small pore sizes together with AB-8 and CAD-40. X-5 is mainly used for the extraction of substances with medium pore sizes. In recent years, with the popularization and rapid development of resin extraction technology, X-5 resin has been effectively applied in the purification of many substances, making significant contributions to the development of the national economy.
The D-101 macroporous adsorption resin is a styrene-type non-polar copolymer (crosslinking agent is divinylbenzene, pore-forming agents are toluene and octanol). It has a broad range of applications and generally exhibits strong adsorption capacity for non-polar or weakly polar organic compounds. It is especially effective for the separation and purification of saponins, and is also suitable for flavonoids and alkaloids. Examples include ginsenosides, notoginsenosides, diosgenin saponins, and ginkgo flavonoids.
The AB-8 type macroporous adsorption resin is a styrene-based weakly polar copolymer (crosslinking agent is divinylbenzene, monomer is methyl acrylate, pore-forming agent is toluene, etc.).
It is suitable for the extraction, separation, and purification of water-soluble substances with weak polarity, such as steviol glycosides and alkaloids.
