Ultisil® Ion Exchange Column
Ultisil® ion exchange columns are available for both Strong Anion Exchange(SAX) and Strong Cation Exchange(SCX) columns. The SCX/SAX columns are silica based with high resolutio ad high efficiecy.
Ultisil® SAX is a polar bonded phase, consisting of an ammonium-functionalized silane while Ultisil® SCX is a classical strog cation.
Features
- Organic modifiers such as acetoitrile and methanol maybe used with SAX and SCX columns, within organic/buffer solubility constraints
- Retention can be controlled by varying pH, ionic strength and organic modifier content.
