Ultisil Ion Exchange columns and media are silica based strong anion exchange (SAX – ammonium-functionalized silane) and strong cation exchange (SCX – covalently bonded aromatic sulfonic acid moiety) columns – with high resolution and high efficiency.
- Organic modifiers such as acetonitrile and methanol may be used with SAX and SCX columns, within organic/buffer solubility constraintsVery lipophilic
- Retention can be controlled by varying pH, ionic strength and organic modifier content.
Ultisil XB-SAX Column are silica based column with high resolution and high efficiency. Ultisil XB-SAX is a polar bonded phase, consisting of an ammonium-functionalized silane. Organic modifiers such as acetonitrile and methanol may be used with SAX Column, within organic/buffer solubility constraints. Retention can be controlled by varying pH, ionic strength and organic modifier content.
