Ion exchange phases

Polymer based

BEKOlut® Leox® AX

This strong anion exchange resin has been developed to improve the performance of conventional silica based mixed-mode anion exchangers for the SPE of weakly acidic analytes.

Typical Application: Extraction of weakly acidic pharmaceutical compounds from aqueous samples and biomatrices.

  • Base material: PS-DVB copolymer
  • Pore size: 70 Angstrom
  • Particle size: 38-55 µm
  • Phase mechanism: anion exchange, reversed phase
