Deliver fast isocratic separation of inorganic anions from diverse and complex matrices such as drinking water, wastewater, foods and beverages, and scrubber solutions with the Thermo Scientific™ Dionex™ IonPac™ AS14A Carbon Eluent Anion-Exchange Column. The Dionex IonPac AS14A column meets or exceeds the requirements of U.S EPA Method 300.0 (A). However, the Dionex IonPac AS22 Carbonate Eluent Anion-Exchange column, an advanced carbonate eluent column, is recommended for fast analysis of inorganic anions. For the fastest separation of inorganic anions using a carbonate/bicarbonate eluent, the Dionex IonPac AS22-Fast column is recommended.
Fast Separation of Inorganic Anions in Diverse Matrices
- Compliance monitoring of common anions in drinking water as specified in U.S. EPA Method 300.0 (A)
- Separation of common inorganic anions in 8 min (3 x 150mm format) or 13 min (4 x 250mm format) in diverse sample matrices
- Superior retention and quantification of fluoride
- Compatible with sodium or potassium hydroxide gradient to optimize difficult separations
- Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components.
Multiple Formats Available for Application Flexibility
- 4x250mm, 3x150mm analytical columns
- 4x50mm, 3x30mm guard columns
- Longer 250mm columns facilitate higher resolution separations of more complex sample matrices
- Shorter 150mm columns produce faster runs of relatively clean matrices
- Smaller i.d. columns provide higher mass sensitivity, eluent and reagent conservation and lower operating costs
Note: Use with the Dionex IonPac AS14 Eluent Concentrate and the Combined Seven Anion Standard for simple, accurate eluent preparation.
