Primesep A is a mixed-mode analytical column with strong acidic ion-pairing groups embedded in long ligand chains. These columns are available in all standard dimensions.

  • Enhances retention of weak basic compounds through cation-exchange mechanism.
  • Separates acids using ion-exclusion mechanism.
  • Retains neutral compounds by reverse-phase mechanism.
  • Offers mobile phase compatibility with LC-MS, preparative chromatography, and low UV detection options.
