"Zhengguang" is specialized in the accurate preparation and application process development of upstream and downstream nano microspheres in biomedicine, and carries out cutting-edge technology research in life science. With a core R & D team with rich technical experience in the development of medium base spheres and functionalization, we have developed four types of chromatographic fillers: polystyrene/divinylphenyl (PS-DVB), polymethacrylate matrix (PMMA), agarose matrix and glucan matrix, and can provide a variety of chromatographic columns.

The company has a modern production line of chromatographic media and a first-class application evaluation laboratory, with accurate preparation technology, surface functionalization technology and large-scale production capacity. The company is committed to becoming one of the world's leading suppliers of chromatographic separation and purification solutions in the field of life science.




Zhengguang Hydrolite SP series high flow rate and high-resolution polymer ion exchange medium

The structure material of the resin separated by ion exchange chromatography is styrene - divinylbenzene, which is prepared by special suspension polymerization process and standardized, and has good chemical and physical stability. Easy loading column, the target component diffusion resistance is small, the product quality is stable.

Therefore, Hydrolite SP series ion exchange chromatography separation resin can not only meet the small process development of fine chemical products such as food and drugs in the laboratory, but also make the process more easily scaled up. The resin with different crosslinking degree has different water content, volume exchange capacity and material diffusion resistance. Such a wide product range enrichis customers' trial choices, and can optimize the appropriate chromatographic separation resin for specific applications.



Hydrolite SPA308A is a strong base anion exchange chromatography medium in the Hydrolite SP series, with quaternary ammonium (Q) strong anion exchange group, particle size 75-150 micron (100-200 mesh), high chemical stability, can perform in place cleaning (CIP) and disinfection processes, It can be used for purification and preparation of small molecules of different scales.

Hydrolite SPA308A application scenario
1.It is used to determine trace levels of rhodium and platinum in environmental biological samples;
2.A strong basic (Type I) anion exchange resin for fine chemicals that meets FDA Food additive regulations;
3.Isolation of inositol phosphate (IP) from myo-[3H] inositol;
4.Isolation of radionuclides;
5.For separating low molecular weight compounds, such as inorganic ions, organic acids, nucleic acids, or carbohydrates;
6.Low crosslinking is used for adsorption and fractionation of relatively high molecular weight substances such as peptides, ribonucleic and deoxyribonucleic acids, and uranium. High crosslinking is used for adsorption, exchange, and separation of low molecular weight inorganic anions, and for applications such as cyclic nucleotide assays and fractional separation of organic acids.

Work hard and keep going. Zhengguang chromatographic medium products fully cover the different stages and application scenarios of upstream and downstream purification, and the performance indicators of products have reached the international advanced level. It provides a strong technical support for the biopharmaceutical field in China, and builds an internationally competitive biopharmaceutical innovation ecosystem.
