Leox CX is a mixed-mode, strongly acidic cation exchange resin, providing a dual retention mechanism and suitable for selective SPE of weakly basic drugs. Also, a step-wise elution is possible for the clean-up of biological samples in toxiclogical analyses. Neutral elution with methanol primarily elutes neutral compounds and only in the second step, weakly basic compounds will elute after addition of 2-5 % ammonia to the organic elution solvent.

Typical Application: Weakly basic pharmaceutical compounds & drugs from aqueous samples and biomatrices

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