Description

General description

Retention Mechanism: Cation exchange
Sample 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
