Gel Strong Acid Cation Activated Styrene/ Polydivinylbenzene Copolymer
Our always-ready technical support and service teams go the extra step to be your most trusted resource. We're here for you.
Chromalite CGC 200x4 is a chromatographic cation exchange resin designed for small organic and inorganic compound separation and purification polymer. It contains 200 μm styrenic resin beads crosslinked with 4% divinylbenzene (DVB). Our proprietary manufacturing method creates perfectly spherical beads with exceptional kinetic and packing properties.
Unlike similar products on the market, our Chromalite CGA and CGC resins are supplied in highly pure form (very low extractables content) and do not require pre-treatment. As such they are suitable for pharmaceutical applications.
- Amberchrom® (formerly Dowex®) (Dow)
- AG 50W-X4 Resin (Bio-Rad)
CGC resins occasionally exhibit colour release into surrounding water after prolonged storage (this will not affect performance).
In such cases it is recommended to rinse the affected resin with sufficient volumes of water to remove this colour release before putting the resin into service.
