Specialty Anion-Exchange IC Columns
Ion exchange columns for special applications
These Thermo Scientific™ IonPac™ columns were designed for special applications such as for non-suppressible eluents in combination with a variety of detection modes, including amperometric and UV-Vis detection. They are useful for separations of higher-valence anions and transition metals.
Specialty anion-exchange IC columns
Column | Recommended Use | Target Applications |
|---|---|---|
| Dionex IonPac AS7 IC Columns | Separation of a wide variety of polyvalent anions, including polyphosphates, polyphosphonates, EDTA and NTA. Method uses postcolumn derivatization and UV-Vis detection | Analysis of polyvalent anions and chelating agents in complex sample matrices, hexavalent chromium in environmental matrices, cyanide and sulfide using amperometric detection. |
| Dionex IonPac AS5 IC Columns | Separation of higher-valence anions including polyphosphates, oxyanions, EDTA complexes, metal cyanide complexes, and hydrophobic anions such as iodide, thiosulfate, and thiocyanate; Dionex IonPac AS16 or AS20 columns recommended for hydrophobic anions and highly-charged anions. | Separations of higher-valence and hydrophobic anions, and rapid elution of strongly retained species such as iodide and thiocyanate in brines without interference from the large chloride peak typical of such samples. |
| Dionex IonPac CS5A IC Columns | Accurate simultaneous determination of common transition and lanthanide metals; high-sensitivity and selectivity in combination with postcolumn derivatization and visible detection at 530 nm; also used for aluminum analysis. | Analysis of transition and lanthanide metals in a variety of sample matrices including high-purity water, plating bath solutions, and power industry waters. |
