The OmniPac® PAX-100 column is a microporous, solvent-compatible, high-capacity, anion-exchange column designed for the separation of hydrophobic anions, and specifically very hydrophobic and halogenated anions. All neutral matrix components are eluted in the void volume.

The OmniPac PAX-100 column was one of the first solvent-compatible, anion-exchange columns for the separation of inorganic and organic anions providing acid and base compatibility over the entire pH range. Because the OmniPac PAX-100 is solvent compatible, solvents can be used to modify the ion-exchange selectivity. Additionally, solvents can be used to solubilize otherwise insoluble samples, or to remove organic impurities from the column to prolong column life. The OmniPac PAX-100 is 100% solvent compatible and should always be run with at least 1% organic solvent in the mobile phase.

OmniPac® PAX-100 Anion-Exchange Column Features:

  • Acid, base, and solvent-compatible, pH 0–14
  • Well suited for the separation of high-molecular-weight organic acids
  • Good for the separation of very hydrophobic anions
  • Good for the separation of halogenated anions

Column Details:

  • Length: 250 mm
  • ID: 4.0 mm
