General description

Retention Mechanism: Cation exchangeSample Matrix Compatibility: Organic or aqueous solutions A polymerically bonded, benzene sulfonic acid functional group, pKa (﹤ 1.0) Counter ion is H⁺ Silica support allows for use with very organic solvents (no shrinking/swelling) Excellent capacity (0.8 meq/g) for cleaning up solution phase combinatorial chemistry reactions (removing target molecules from reaction by-products and excess reagents) The presence of the benzene ring offers some mixed-mode capabilities (hydrophobic interactions) that should be considered when extracting cations from aqueous matrices
