DuPont™ AmberLite™ CR7300 Resin
DuPont™ AmberLite™ CR7300 resin is a strong base anion resin manufactured through a process that ensures extremely uniform particle size. Purpose-built for simulated moving bed (SMB) chromatographic systems, it delivers superior performance in the separation of mono- and dicarboxylic acids as well as specialty sugars.
Designed with an optimal balance of particle size and rapid kinetics, DuPont™ AmberLite™ CR7300 resin enhances separation efficiency while minimizing product dilution. This improved performance helps reduce water evaporation costs, which is especially valuable when fractionating mono- and dicarboxylic acids from residual dextrose and other acids. For these applications, the resin is typically converted to the sulfate form for additional ionic stability.
Uses
- Organic acid chromatography
- Purification of organic acids from dextrose and other carbohydrates
- Chromatographic separation for specialty sugars
- Specialty separations
Advantages
- Uniform particle size for lower separation system water consumption and pressure drop
- Enhanced separation kinetics from smaller particle size
- Rigid bead design to resist compression in packed beds
- Tailored resin microporosity to maximize separations performance
