Separate higher-valence anions, including polyphosphates, oxyanions, EDTA complexes, metal cyanide complexes, and hydrophobic anions such as iodide, thiosulfate, and thiocyanate with Thermo Scientific™ Dionex™ IonPac™ AS5 Analytical Columns. IonPac polymeric columns address a variety of chromatographic separation modes including ion exchange, ion exclusion, reversed-phase ion pairing, and ion suppression.
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.
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
Note: IonPac AS16 or AS20 columns are recommended for hydrophobic anions and highly-charged anions
