Agilent SampliQ WAX weak anion exchange solid phase extraction cartridges is suitable for strongly acidic, acidic and neutral compounds. It has excellent reproducibility, high recoveries and spherically controlled particles.
This document introduces Agilent's SampliQ WAX solid-phase extraction (SPE) cartridges, which utilize a weak anion exchange polymeric resin. The resin is designed to extract strongly acidic, acidic, and neutral compounds, offering advantages such as excellent reproducibility, high recoveries, and stability across a wide pH range (0 to 14). It is particularly useful for cleaning extracts to reduce ion suppression in LC/MS/MS or GC/MS/MS analyses.

It is designed for the extraction of strongly acidic, acidic, and neutral compounds.
No, the cartridges are intended for single use, and reconditioning is not recommended.
The pH of the loading solution should be approximately 1 to 2 for the strongest retention of acids and neutrals.
