Product Description
The SUGAR KS Guard Columns 50x8.0mm, 20µm, protect SUGAR KS HPLC guard columns against particles and strongly bound matrix components. These are prepacked guard columns that can be connected directly in front of the separation column without a separate cartridge holder.
Features and Benefits
- Polymer-based carbohydrate phases
- Multiple defined counterions
- Ligand- and ion-exchange mechanisms
- Elution with pure water is often possible
- For sugars, acids, and fermentation samples
Additional Notes
The SUGAR product family is based on sulfonated styrene-divinylbenzene resins with defined counterions such as calcium, lead, sodium, zinc, or hydrogen. The counterion controls ligand exchange with hydroxyl groups, while pore size and polymer crosslinking determine the size-exclusion component. Columns in the hydrogen form additionally enable ion exclusion for organic acids. Since selectivity depends heavily on temperature, counterion, and water quality, the recommended operating conditions should be strictly adhered to.
