Bond Elut™ SCX is a strong cation exchanger with a very low pKa. Although the pKa is similar to Bond Elut™ PRS, the presence of the benzene ring in the functional group increases the potential for non-polar interactions. This non-polar characteristic becomes particularly important when conducting ion-exchange from aqueous systems, where selectivity towards compounds exhibiting cationic and non-polar character is seen.

• Useful for compounds with both cationic and non-polar characteristics
• Superior cleanup from a single sorbent
• Very low pKa ligand elicits strong analyte interaction
