Extrasil SAX, 5μm, 4.6×250mm HPLC Analytical Column

(0 review)

Extrasil 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.
Extrasil SAX is a polar bonded phase, consisting of an ammonium-functionalized silane, while Extrasil SCX is a classical strong cation exchange, consisting of a covalently bonded aromatic sulfonic acid moiety.
• Organic modifiers 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 ranges from 2.0 to 7.0
