A weak cation exchanger with a pKa of 4.8. A pH of 2.8 or below is needed to neutralize the phase and easily elute strong cationic analytes that are neutralized only at extreme basic conditions. This phase is commonly used for the extraction of strong cationic species, which would bind too strongly to strong cation exchangers.
