Features
- IONEX-25 SA-Na: mixture of silica and a strongly acidic cation exchanger coated to polyester sheets
- IONEX-25 SB-AC: mixture of silica and a strongly basic anion exchanger coated to polyester sheets
- Both layers contain an inert organic binder.
Recommended application: amino acids, e.g., in protein and peptide hydrolysates, in seeds and fodder, in biological fluids; for racemate separation in peptide syntheses, for the separation of nucleic acid hydrolysates, aminosugars, aminocarboxylic acids, antibiotics, inorganic phosphates, cations and other compounds with ionic groups.
