Industrial Chromatography
Designed specifically for compliance monitoring of inorganic anions in accordance with U.S. EPA Methods 300.0 (A), the Thermo Scientific™ Dionex™ IonPac™ AS22 Analytical, Capillary & Guard Columns provide fast analysis of drinking water, ground water and wastewater. With the Dionex IonPac AS22 column, using a simple isocratic carbonate/bicarbonate eluent, common inorganic anions can be quickly separated in a variety of sample matrices including drinking water, wastewater, process streams, and scrubber solutions.

Description

Analysis of Common 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)
  • Fast isocratic separation of common inorganic anions in simple matrices in 8 min.
  • Isocratic separation of common inorganic anions in complex matrices in 12 min.
  • Excellent retention of fluoride from the water dip and resolution of fluoride, acetate, and formate
  • Excellent resolution of the carbonate peak away from peaks for common inorganic anions
  • Ideal alternative, using carbonate/bicarbonate eluents, for IonPac AS4A-SC, AS12A, AS14 and AS14A inorganic anion applications.
  • Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components.

Reduce Operating Costs With Lower Eluent Requirements

The IonPac AS22 Capillary column provides the same performance as the standard bore and microbore IonPac AS22 columns because it is packed with the same material. Operating costs are reduced because the capillary system operates at only 1% of the eluent flow rate of the standard bore system, requiring less eluent and producing less waste.

Multiple Formats Available for Application Flexibility

  • 4x250mm, 2x250mm analytical columns
  • 4x50mm, 2x50mm guard columns
  • 0.4x250mm capillary column, 0.4x50mm capillary guard column
  • Longer 250mm columns facilitate higher resolution separations of more complex sample 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 IonPac AS22 Eluent Concentrate.
