IonPac AS5 Specialty Anion-Exchange Column

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.

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

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.

Note: IonPac AS16 or AS20 columns are recommended for hydrophobic anions and highly-charged anions.
