For Separating Higher-Valence Anions.

The IonPac® AS5 separates higher-valence anions, including polyphosphates, oxyanions, EDTA complexes, metal cyanide complexes, and hydrophobic anions such as iodide, thiosulfate, and thiocyanate.

The AS5’s compatibility with weak eluents simplifies the determination of strongly-retained species, since these eluents are compatible with a suppressor. Furthermore, the rapid elution of strongly-retained species greatly improves peak shapes, lowers minimum detection limits, and increases sample throughput potential.

The selectivity of the AS5 makes it possible to rapidly elute strongly-retained species such a iodide and thiocyanate in brines without interference from the large chloride peak typical of such samples.

IonPac® AS5 Specialty Anion-Exchange Column Features:

  • For metal-EDTA complexes
  • For cyano-transition metal complexes
  • For hydrophobic anions, including iodide, thiocyanate, and thiosulfate
  • AS16 or AS20 columns are recommended for hydrophobic anions and highly charged anions

Column Details:

  • Particle Size: 15 µm
  • Length: 250 mm
  • ID: 4.0 mm
