201×7MB Strong-Base Type I (Gel) Anion Exchange Resin

1. Description
201×7MB is a clear gel Type 1 strong-base anion exchanger with both high operating capacity and the ability to achieve low residual silica levels. It has a clear gel structure, showing excellent regeneration efficiency and rinse characteristics. 201×7FC has exceptional physical stability for a conventional gel-type resin which permits a long life without the development of excessive pressure drop; it also shows good kinetics of exchange, enabling very low concentration levels of both strong and weak anions to be achieved at practical flowrates
