일반 설명

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

Solid Phase Extraction: Ion Exchange Methodology

SPE retention mechanism in this case is based on the electrostatic attraction of charged functional groups of the analyte(s) to oppositely charged functional groups on the sorbent.

Analysis of Melamine in Milk

Melamine was extracted from milk using Supelco® Discovery® DSC-SCX SPE tubes. Analysis was performed by HPLC, using an Ascentis® Express HILIC column.

Solid Phase Extraction: Normal Phase Methodology

Retention occurs through polar interaction between the sorbent and analytes. Typical sample matrices that can be employed in normal-phase SPE include hydrocarbon or fatty oils diluted in a solvent like hexane, isooctane, chlorinated solvent, THF, diethyl ether, or ethyl acetate.
