Description
Hi-PuritTM WCX
- A moderate polarity sorbent and weak cation exchanger [pKa 4.8]/li>
- Cation exchange with no need for extreme basic conditions
- Wider selectivity range provides more eluent options
- Polar or non-polar depending on matrix or solvent
- Typically used when dealing with very strong cationic [high pKa] compounds that may be irreversibly retained on strong cation exchangers
