In stirred tank processes, resin captures either impurities or target product and is then filtered to isolate the filled resin. Captured product is recovered by washing the product from the resin with a rinse or pH cycle, regenerating the resin for additional use. In the case of captured impurities, the loaded resin can be discarded as waste in single-use designs, or the resin can be regenerated for additional use by releasing impurities. DuPont™ offers a range of fine mesh ion exchange resins and polymeric adsorbents that allow end-users to balance desorption kinetics and binding capacity.
