Primesep 500 is a mixed-mode analytical column with acidic ion-pairing groups embedded into long ligand chains.

  • Contains an embedded carboxilic acid group with a pKa of about 5
  • Improves retention of basic compounds by cation-exchange mechanism with a mobile phase of pH > 5
  • Separates acids by ion-exclusion mechanism with a mobile phase of pH > 5
  • Retains basic compounds, like any reverse phase column, at pH < 5
  • Retains neutral compounds by reverse-phase mechanism
  • All mobile phases are LC-MS and preparative chromatography compatible
