Description

Solid phase extraction (SPE) is a technique commonly used in laboratories to isolate analytes of interest from complex matrices.

Retention Mechanism: Cation exchangeSample Matrix Compatibility: Organic or aqueous solutions. A polymerically bonded, ethylenediamine triacetic acid phase with a pKa of 4.8. Counter ion is Na+. Ion exchange capacity is >= 0.15 meq/g. Carries a negative charge at pH 6.8 or above. A pH of 2.8 or below neutralizes this phase for easier elution of strong cationic analytes that are neutralized only at extreme basic conditions. Typically used when dealing with very strong cationic (high pKa) compounds that may be irreversibly retained on strong cation exchangers
