Discovery® DSC-SCX SPE Tube, 1 X 20 ea (52690-U)

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
