Description
Hi-PuritTM SAX
- A polymerically bonded quartemary amine that remains changed at all ph leveles
- Retains negatively charged componends, especially those that clute from weak anion exchange sorbents
- Selectivity can be user-modified for increased flexibility
- Minimal non-polar interactions.
