General description
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
