Watrex Polymer IEX™ is the Europe’s leading sorbent for ion exclusion analysis of alcohols, carboxylic acids, sugars, and polysacharides
- H⁺, Ca²⁺, Pb²⁺ and Na⁺ forms
- Unique monodispersed sorbent based on sulfonated polystyrene
- Bulk packing materials available
H form
The hydrogen form is suitable for organic acids, alcohols and some sugars in natural materials. The column is particularly suitable for the analysis of fruit drinks, wine, etc. Its great advantage is the high stability of retention times and the wide concentration range of analytes.
Watrex: Column 250x8mm IEX H
Ca form
The calcium form is characterized by good selectivity for the separation of mono- and disaccharides in natural materials. The column must be protected from anions forming insoluble calcium salts (phosphates, sulphates, etc.) and cations with a higher affinity for the sorbent than calcium ions.
Watrex: Column 250x8mm IEX Ca
Pb form
The lead form is suitable for the separation of mono- and disaccharides in natural materials. The column must be protected from anions forming insoluble lead salts (phosphates, sulphates, etc.) and cations with a higher
Use the appropriate pre-column to extend the life of the analytical column.
