Shodex RSpak Mixed-Mode HPLC Columns
Shodex RSpak NN-814 and JJ-50 2D are polymer-based mixed-mode columns with reversed phase and ion exchange functionalities.
RSpak NN-814
- Modified with sulfo groups supports multimode (reversed phase and cation exchange) analysis
- Ideal for the analysis of complex samples containing neutral and ionic substances
- Suitable for the separation of water-soluble substances such as nucleotides, nucleosides, nucleobases, water-soluble vitamins, and amino acids
RSpak JJ-50 2D
- 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
- RSpak NN-814 is a polymeric based column modified with sulfo groups
- RSpak JJ-50 2D is a polymeric based column modified with trace amounts of quaternary ammonium groups
- Ideal for analysis of complex samples containing neutral and ionic substances
- Separation of the sample can be controlled by changing organic strength, pH, salt concentration and temperature
