Dionex™ IonPac™ AS7 IC Columns
Related applications:
For separation of a wide variety of polyvalent anions, including polyphosphates, polyphosphonates, and other polyvalent complexing agents, the Thermo Scientific™ Dionex™ IonPac™ AS7 anion-exchange column delivers excellent results. The column has a unique polymer packing that provides superior performance for separating ionic and polar compounds that offers high speed, high efficiency, and high loading capacity at moderate backpressures. However, the newer Dionex IonPac AS16 column is recommended for determination of polyphosphates.
Analysis of Polyvalent Anions and Chelating Agents in Diverse Matrices
- Analyze hexavalent chromium in environmental matrices in accordance with U.S. EPA Method 218.6
- For separation of polyvalent anions and chelating agents in complex sample matrices using a post column reagent and UV detection
- Determines cyanide, sulfide and iodide in high ionic strength matrices using amperometric detection
- Typically used with post column reagents for photometric detection
- Contains both anionic and cationic ion-exchange capacity
- Compatible with a wide range of eluents and detectors for sensitive and selective analysis
- 4 x 250mm, 2 x 250mm analytical columns
- 4 x 50mm, 2 x 50mm guard columns
- Longer 250mm columns facilitate higher resolution separations of more complex sample matrices
- Smaller i.d. columns provide higher mass sensitivity, eluent and reagent conservation and lower operating costs
