RSpak columns

RSpak NN-814 and JJ-50 2D

Polymer-based RP and mixed-mode columns for many different applications

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
