The OmniPac®PCX-500 column is a macroporous, high-capacity, solvent-compatible column designed to separate cationic and neutral species in a single run. This column combines cation-exchange and polymeric reversed-phase retention mechanisms in a single column.
Good for the simultaneous separation of neutral and cationic species
Acid and base compatible, pH 0–14
100% solvent compatible
Not as effective as the CS12A for inorganic cations
The multimode separation mechanism is achieved by coating a macroporous hydrophobic core for reversed-phase retention with a cation-exchange latex bead layer for cation-exchange retention. The macroporous structure provides an accessible hydrophobic core where reversed-phase retention occurs. The cation-exchange selectivity is provided by a cation-exchange MicroBead™layer that coats the hydrophobic core. Since the cation-exchange layer is identical to that of the OmniPac PCX-100, the two columns exhibit similar ion-exchange selectivity. As a result, the OmniPac PXC-100 can be used to develop the ion-exchange separation, and the method can then be transferred to the OmniPac PXC-500 for further refinement to include solvent for the reversed-phase separation. The OmniPac PCX-500 is 100% solvent compatible and should always be run with at least 1% organic solvent in the mobile phase to maintain column life.
The OmniPac PCX-500 may be used for the separation of compounds such as adrenergics, alcohols, anilines, antidepressants, anti-inflammatory agents, plating bath brighteners, cephalosporins, stains and dyes, herbicides, nucleotides and nucleosides, peptides, sulfonamides, and water-soluble vitamins.
