IonPac AS22-快速碳酸盐洗脱液阴离子交换柱

IonPac AS22-Fast Carbonate Eluent Anion-Exchange Column

Super Fast Analysis of Common Inorganic Anions

Designed specifically for compliance monitoring of inorganic anions in accordance with US EPA Method 300.0 (A) and 300.1, the IonPac^® AS22-Fast represents the culmination of more than 20 years of column development, and is a key complement to our award-winning Reagent-Free^™ IC system.

• Super-Fast isocratic separation of the common inorganic anions in under 5 minutes

• Carbonate peak well-resolved from the common inorganic anions

• Same selectivity as AS22 column

• Meets performance requirements specified in US EPA Method 300.0 (A)

• Fast alternative for AS4A-SC, AS12A, AS14, AS14A, and AS22 inorganic anion applications

• Simple, accurate eluent preparation with the AS22 Eluent Concentrate

• Optimized for a 30 °C operating temperature to ensure reproducible retention times

The AS22-Fast 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 AS22-Fast 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 AS22-Fast can be used in combination with the Eluent Generator and the Electrolytic pH Modifier (EPM) which automatically produce potassium carbonate/bicarbonate eluents from water. The AS22-Fast column is the newest carbonate eluent column recommended for super fast analysis of inorganic anions and is a faster alternative, using carbonate-bicarbonate eluents, for AS4A-SC, AS12A, AS14, AS14A, and AS22 inorganic anion applications.

Note: Use the Anion Self-Regenerating Suppressor (ASRS^® 300) with the AS22-Fast column for eluent suppression.
