Ion Pair Reagents

Ion pair reagents are strongly hydrophobic ions which form neutral ion pairs with oppositely charched sample molecules. This way, the simultaneous separation of charged and non-charged molecules is possible.
By adding ion pair reagents to the sample solution in RP-HPLC, strong bases are "masked" and retard in neutral form on RP surfaces.


  • High purity
  • High UV-permeability
  • Broad range of products
  • Excellent price/performance ratio
