Polymer-based (Quaternary ammonium) Reversed Phase RP and mixed-mode columns for many different applications

Specifications:

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

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

• A mixture of water and acetonitrile or water and methanol of any ratio can be used. Use of organic solvents other than acetonitrile or methanol will not be covered under warranty.

• Buffers and aqueous solutions of different salts can be used instead of water. They include phosphate, acetate, and Tris buffers and aqueous solutions of sodium chloride, potassium chloride, and sodium sulfate. Please keep total concentration of salts under 0.1 M.

Cleaning/Regeneration

• Insoluble components that block the column inlet may be removed by reversing the flow direction, i.e., introducing the eluent from the column outlet, with flow rate at less than half of the recommended flow rate.
• Follow below cleaning steps for adsorbing components. For an efficient cleaning, reverse the flow direction and use the flow rate at 0.1 mL/min:

(Pollution by low valency hydrophilic ions)

1. H2O 6 min
2. 0.1 M NaOH aq. 75 min
3. H2O 12 min
4. Eluent 40 min

(Pollution by metal ions)

1. H2O 6 min
2. 0.1 M HNO3 aq. 75 min
3. H2O 6 min
4. 0.1 M NaOH aq. 75 min
5. H2O 12 min
6. Eluent 40 min

(Pollution by high valency hydrophobic ions)

1. H2O 25 min
2. 5 % acetonitrile aq. 20 min
3. 100 % acetonitrile 100 min
4. H2O 50 min
