Ultisil SAX
– 10 columns
Vendor: Welch Materials
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 resolution and high efficiency. Ultisil SAX is a polar bonded phase, consisting of an ammonium-functionalized silane, while Ultisil SCX is a classical strong cation exchange, consisting of a covalently bonded aromatic sulfonic acid moiety.
- Organic modifi ers such as acetonitrile and methanol may be used with SAX and SCX columns, within organic/buffer solubility constraints
- Retention can be controlled by varying pH, ionic strength and organic modifier content
- Stable pH range from 2.0 to 7.0
