Discovery(R) DSC-SCX SPE Tube

Descrição detalhada : 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
