Description

Weak anion exchanger ideal for extracting strong basic compounds that remain charged at all pH levels.

Retention Mechanism: Anion-exchange. Sample Matrix Compatibility: Organic or aqueous Solutions. Weak anion exchanger ideal for extracting strong basic compounds that remain charged at all pH levels. Unlike conventional weak anion exchange SPE phases such as -NH2 (aminopropyl) that have a pKa of 9-10, a pH = 7. This characteristic is important for extracting analytes that are not stable (e.g. hydrolyzes) at high pHs typically required for elution when using traditional weak anion exchangers. Ideal for extracting acyl-coenzyme A esters from tissue.
