Chromalite CGA200x2 is a chromatographic anion exchange resin with a polymer designed for small organic and inorganic compound separation and purification. It contains 200 μm styrenic resin beads crosslinked with 2% divinylbenzene (DVB). Our proprietary manufacturing method creates perfectly spherical beads with exceptional kinetic and packing properties.
Unlike similar products on the market, 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.
Equivalent to:
- Dowex® 1X2 50-100 mesh (Dow)
- AG 1-X2 Resin (Bio-Rad)
Note:
CGA resins occasionally exhibit an amine odour 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 the odour before putting the resin into service.| Appearance | Pale yellow to dark yellow spherical beads | |
