| | | | IonPac AS5 Anion-Exchange Column |
| The IonPac® AS5 is a low-capacity, hydroxide-selective, anion-exchange column designed for the separation of higher-valence anions, including polyphosphates, oxyanions, EDTA complexes, metal cyanide complexes, and hydrophobic anions such as iodide, thiosulfate, and thiocyanate. The AS16 column is recommended for hydrophobic anions and polyphosphates. Use the AS5 column for metal-EDTA complexes. Use the AS5 column for cyano-transition metal complexes. The AS5 can be used for hydrophobic anions, including iodide, thiocyanate, and thiosulfate. The high-capacity AS16 or AS20 columns are recommended for hydrophobic anions and highly charged anions.
