by SIELC

Primesep 500 is a reverse-phase analytical column with embedded acidic ion-pairing groups.

  • Primesep 500 has an embedded carboxilic acid with a pKa of about 5.
  • Improves retention of basic compounds by cation-exchange mechanism at pH > 5.
  • Separates acids by ion-exclusion mechanism at a mobile phase pH > 5.
  • Retains basic compounds, as any RP column, at pH < 5
  • Retains neutral compounds by reverse-phase mechanism.
  • All mobile phases are LC-MS and preparative chromatography compatible.
