Antibiotics Purification

Separation technique based on ion exchange & adsorbent system

Ion exchange and adsorption is an efficient and low-cost separation technique that has been widely used in the pharmaceutical industry. It is primarily a way to achieve separation and purification on a large scale with ion exchange systems with complex and designable ion exchange resins. It removes impurities, concentrates the target, and produces highly pure pharmaceuticals.

Sunresin has developed a group of CephalosporinsC (CPC) purification resins, including pretreatment, separation and decolorization years ago. Up to now Sunresin is the main CPC resin supplier worldwide.

SEPLITE® resins for pharmaceuticals are effective in decolorization & purification of fermentation liquor in antibiotics, vitamins, proteins and other medical applying chemicals.

As the first and the only A-share listed company in Chinese ion exchange and adsorbent resin industry, Sunresin took the lead in researching the resin for cephalosporin C purification and promote the rapid development of China's cephalosporin antibiotic industry. Chinese cephalosporin producers like to use Sunresin's purification technology.
