Agilent SampliQ SCX is a solid phase extraction (SPE) product that offers excellent reproducibility and high recoveries even when dried. It is suitable for basic and neutral compounds, with a simple extraction protocol and controlled particle size.
The document describes the Agilent SampliQ SCX resin, a sulfonic acid modified divinyl benzene polymer that exhibits both cation exchange and reversed phase behavior. It is designed for the extraction of basic and neutral compounds with high reproducibility and recovery rates, even when dried. The resin is stable in pH ranges from 0 to 14.
The flow through the cartridge should be no faster than 1 mL/min.
Methanol is typically used first, followed by an aqueous solution like 2% formic acid in water.
