Bond Elut™ plexa PAX non-polar/anion-exchange polymeric SPE offers excellent clean-up and reproducibility, and is suitable for polar and non-polar acidic analytes.

• Mixed mode nonpolar polymeric anion exchanger offers high level of analyte selectivity
• Exclusion of endogenous interferences offers superior cleanliness and minimises ion suppression
• Simple, single method for ease-of-use reduces method development time

Existing polymeric anion-exchange sorbents can exhibit a broad range of ion exchange capacity from batch to batch. This leads to nonreproducible methods and compromised data. Plexa PAX particles are functionalised using a proprietary process, which allows anion exchange loadings to be controlled with a high degree of reproducibility, allowing a more robust performance across the lifetime of your compound study or method.
