Fast, High Resolution Analysis of Common Inorganic Anions
Attain the optimal combination of speed and resolution using the new Thermo Scientific? Dionex? IonPac? AS22-Fast-4μm anion-exchange column. This moderate capacity, high efficiency column provides excellent resolution of inorganic anions in environmental matrices. Compared to the previous Dionex IonPac AS22-Fast column, the new anion-exchange column uses smaller resin particles for more efficient separations resulting in faster run times, more accurate peak integration and more reliable results. Designed specifically for compliance monitoring of inorganic anions in accordance with U.S. EPA Method 300.0 (A) and 300.1, the Dionex IonPac AS22-Fast-4μm column represents the culmination of more than 25 years of column development, and is a key complement to our award-winning Reagent-Free? IC system.
Fast, high resolution isocratic separation of the common inorganic anions in under 5 minutes
Carbonate peak well-resolved from the common inorganic anions
Same selectivity as the Dionex IonPac AS22-Fast column
Meets performance requirements specified in US EPA Method 300.0 (A) and 300.1
Fast alternative for Dionex IonPac AS4A-SC, AS12A, AS14, AS14A, and AS22 inorganic anion applications
Simple, accurate eluent preparation with the Dionex IonPac AS22 Eluent Concentrate
Optimized for a 30 °C operating temperature to ensure reproducible retention times
The Dionex IonPac AS22-Fast-4μm column is designed for the fast determination of inorganic anions and low molecular weight organic acids including fluoride, acetate, formate, chloride, nitrite, bromide, nitrate, phosphate, and sulfate. The Dionex IonPac AS22-Fast-4μm column can be used with isocratic carbonate/bicarbonate eluents and suppressed conductivity detection. Common inorganic anions can easily be separated in a variety of sample matrices including drinking water, wastewater, process streams, and scrubber solutions.
The Dionex IonPac AS22-Fast-4μm can be used in combination with the new Eluent Generator, (Thermo Scientific Dionex EGC 500 K2CO3 Cartridge) and the Electrolytic pH Modifier (Thermo Scientific Dionex EPM 500) which automatically produce potassium carbonate/bicarbonate eluents from water. The Dionex IonPac AS22-Fast-4μm column is the newest carbonate eluent column recommended for fast analysis of inorganic anions and is a faster alternative, using carbonate-bicarbonate eluents, than Dionex IonPac AS4A-SC, AS12A, AS14, AS14A, and AS22 inorganic anion applications.
Note: Use the Dionex Anion Electrolytically Regenerated Suppressor (Thermo Scientific? Dionex? AERS? 500 suppressor) with the Dionex IonPac AS22-Fast-4μm column for eluent suppression.
