Designed specifically for compliance monitoring of inorganic anions in accordance with U.S. EPA Method 300.0 (A) and 300.1, the new IonPac® AS22 represents the culmination of more than 20 years of column development, and is a key part of our award winning Reagent-FreeTM IC system, a revolutionary step in ion chromatography that requires only a source of deionized water to produce potassium carbonate/bicarbonate eluent. Fast isocratic separation of the common inorganic anions in simple sample matrices in 6 minutes. Isocratic separation of inorganic anion in complex sample matrices in 12 minutes. Carbonate peak well-resolved from the common inorgainc anions. Meets performance requirements specified in U.S. EPA Method 300.0 (A). Ideal alternative for AS4A-SC, AS12A, AS14, and AS14A inorganic anion applications. Simplified Reagent-Free IC operation provided by the EG50 Eluent Generator and EPM, which require only a deionized water source to produce potassium carbonate/bicarbonate eluent. Simple, accurate eluent preparation with the AS22 Eluent Concentrate—just dilute in deionized water and start operation. Eluent suppression using the ASRS® ULTRA or AAES® technology provides Reagent-Free IC operation with low backgrounds and enhanced analyte sensitivity. High Capacity: 210 µeq/col. (4 x 250 mm column). Operate at ambient or elevated temperatures. Column selectivity is optimized for a 30 °C operating temperature to ensure reproducible retention times. Compatible with organic solvents to enhance analyte solubility, modify column selectivity, or for effective column cleanup.
The IonPac AS22 is a carbonate-based anion-exchange column designed for the determination of inorganic anions and low molecular weight organic acids including fluoride, acetate, formate, chloride, nitrite, bromide, nitrate, phosphate, and sulfate. The AS22 column can be used with isocratic carbonate/bicarbonate eluents and suppressed conductivity detection for the determination of inorganic anions. The AS22 column can be used in combination with the EG50 Eluent Generator and the Electrolytic pH Modifier (EPM) which automatically produces potassium carbonate/bicarbonate eluents from water. The AS22 column is an ideal alternative, using carbonate-bicarbonate eluents, for AS4A-SC, AS12A, AS14, and AS14A inorganic anion applications. The IonPac AS22 column meets the performance requirements specified in U.S. EPA Method 300.0 (A). The common inorganic anions can easily be separated in a variety of sample matrices including drinking water, wastewater, process streams, and scrubber solutions. Use the Anion Self-Regenerating Suppressor (ASRS ULTRA II) or Anion Atlas® Electrolytic Suppressor (AAES) with the AS22 column for eluent suppression.
