Product information

The RSpak NN-814 and JJ-50 2D combine the reversed phase (RP) mode with ion exchange chromatography (IEC)

RSpak NN-814

  • The packing material modified with sulfo groups supports multimode (reversed phase and cation exchange) analysis

  • Ideal for the analysis of complex samples containing neutral and ionic substances

  • suited for the separation of water-soluble substances such as nucleotides, nucleosides, nucleobases, water-soluble vitamins and amino acids

 

RSpak JJ-50 2D

  • The packing material is modified with trace amounts of quaternary ammonium groups, and supports multimode (reversed phase and anion exchange) analysis

  • Ideal for analysis of complex samples containing neutral and ionic substances
