General description

Supelclean™ LC-SCX SPE Tubes consist of sulfonic acid bonded silica with Na+ counterions. They can be used for the strong cation exchange of cations, antibiotics, drugs, organic bases, amino acids, catecholamines, herbicides, nucleic acids and bases, nucleosides, and surfactants.

Application

Supelclean™ LC-SCX SPE Tube may be used for the solid-phase extraction of β-agonist compounds in feed samples and adulterants in slimming functional foods prior to their quantification by chromatographic techniques.

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.

Protocols

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.
