Both strong anion exchange (SAX) and strong cation exchange (SCX) columns are bonded with spherical silica particles for optimum efficiency. SAX is ideal for separation of water-soluble compounds such as aromatic and aliphatic carboxylic acids and sulphonic acids and SCX is ideal for separations of basic, water-soluble compounds and bio-molecules.

• Stable from pH 2 to 7
• Provide high efficiency, rapid separations
• Compatible with organic mobile phase modifiers
• A trifunctional organo silane reagent is used in producing ZORBAX® SAX packing to maximise its stability with aqueous mobile phases
