Designed specifically for compliance monitoring of inorganic anions in accordance with U.S. EPA Methods 300.0 (A), the Thermo Scientific™ Dionex™ IonPac™ AS22 IC Columns provide fast analysis of drinking water, ground water and wastewater. With the Dionex IonPac AS22 column, using a simple isocratic carbonate/bicarbonate eluent, common inorganic anions can be quickly separated in a variety of sample matrices including drinking water, wastewater, process streams, and scrubber solutions.
Analysis of Common Inorganic Anions and Low Molecular Weight Organic Acids in Diverse Matrices
- Compliance monitoring of common anions in drinking water as specified in U.S. EPA Method 300.0 (A)
- Fast isocratic separation of common inorganic anions in simple matrices in 8 min.
- Isocratic separation of common inorganic anions in complex matrices in 12 min.
- Excellent retention of fluoride from the water dip and resolution of fluoride, acetate, and formate
- Excellent resolution of the carbonate peak away from peaks for common inorganic anions
- Ideal alternative, using carbonate/bicarbonate eluents, for IonPac AS4A-SC, AS12A, AS14 and AS14A inorganic anion applications.
- Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components.
Multiple Formats Available for Application Flexibility
- 4x250mm, 2x250mm analytical columns
- 4x50mm, 2x50mm 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
Note: For simple, accurate eluent preparation, use the IonPac AS22 Eluent Concentrate.
