Thermo Scientific* OmniPac* PAX-500 HPLC Columns

When you need to separate anionic and neutral species in a single run, use the Thermo Scientific OmniPac PAX-500 Column. With anion-exchange and reversed-phase properties, this polymer-based mixed-mode column is solvent compatible and stable over the entire pH range of 1-14. Solvents may be used to affect selectivity as well as to remove contaminants to extend column lifetime. The OmniPac PAX-500 column is ideal for analysis of a wide range of compounds.

Specifications
The OmniPac PAX-500 column is ideal for analysis of alcohols, alkanolamines, antihistamines, anti-inflammatory agents, aromatic acids, inorganic acids, peptides, purines and pyrimidines, sulfonamides, sulfonated anionic surfactants, and water-soluble vitamins.

• Macroporous hydrophobic core provides reversed-phase retention and is coated with an anion-exchange latex bead layer for anion-exchange retention
• Ion exchange capacity of approximately 40µeq/column
• 100% solvent-compatible and should always be run with at least 1% organic solvent in the mobile phase
