Quat. ammonium modified silica gel, strong basic anion exchanger (SAX)
- Scavenger for weak acids, sulfonyl chlorides, isocyanates, biomolecules and weak electrophiles
Retains weaker anions such as carboxylic acids, sulphonic acids and phosphates that may not be retained strongly enough on weaker anion exchange phases
Please note: Not suitable for very strong anions such as sulphonic acids because they are difficult to elute.
