Technical Specifications


• Polymer-based cation exchange column

• Weak Carboxymethyl groups (WCX - weak cation exchange)

• Suitable for analyzing relatively high molecular weight compounds: proteins, peptides, DNA, and RNA

• Compared to IEC series columns, polyvinyl alcohol is used as base material and this offers different separation pattern

• Low hydrophobic interaction with proteins allows analysis under mild conditions
