IonPac AS5专业阴离子交换柱

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.
