IonPac AS22

by Dionex

 

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

  • Fast isocratic separation of the common inorganic anions in 8 minutes
  • Isocratic separation of inorganic anions in complex sample matrices in 12 minutes
  • Carbonate peak well-resolved from the common inorganic anions
  • Meets performance requirements specified in US EPA Method 300.0 (A)
  • Ideal alternative for AS4A-SC, AS12A, AS14, and AS14A 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 is 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 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.

Similar columns from other manufacturers to IonPac AS22

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated
Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.
A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.
