Designed specifically for compliance monitoring of inorganic anions in accordance with U.S. EPA Methods 300.0 (A), the Thermo Scientific™ Dionex™ IonPac™ AS22-Fast column combines the selectivity of the Dionex IonPac AS22 column with super-fast separation times. With the Dionex IonPac AS22-Fast column, you can quickly and simply separate common inorganic anions from a variety of sample matrices including drinking water, wastewater, process streams, and scrubber solutions.
Super Fast Analysis of 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)
- Super-fast isocratic separation of common inorganic anions in less than 5 min in diverse matrices such as drinking water, surface water, groundwater, and wastewater
- Sufficient capacity to maintain resolution even in a short column format, which helps laboratories achieve higher productivity and increased throughput
- Excellent resolution of the carbonate peak away from the common inorganic anions
- Faster alternative, using carbonate/bicarbonate eluents, for Dionex IonPac AS4A-SC, AS12A, AS14, AS14A and AS22 inorganic anion applications.
- Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components.
Multiple Formats Available for Application Flexibility
- 4x150mm, 2x150mm analytical columns
- 4x30mm, 2x30mm guard columns
- 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: For simple, accurate eluent preparation, use the Dionex IonPac AS22 Eluent Concentrate.
