• Achieve the highest peak efficiency for common inorganic anions in different sample matrices by using smaller resin particles
• Rapid isocratic separation of common inorganic anions in less than 5 minutes
• Compliance monitoring of common anions in drinking water as described in U.S. EPA Method 300.0 (A)
• Excellent separation of inorganic anions and low molecular weight acids in a variety of sample matrices
• Achieve extremely high peak efficiency and improved resolution for more consistent integration and more reliable results
• Easily transfer applications—this 4µm column has the same selectivity as Dionex IonPac AS22-Fast columns
• Achieve excellent separation between carbonate peaks and common inorganic anion peaks Resolution
• Shortened run times compared to Dionex IonPac AS22-Fast columns, but resolution is not affected
• Using carbonate/bicarbonate eluents, yes An alternative for faster Dionex IonPac AS4A-SC, AS12A, AS14, AS14A and AS22 inorganic anion applications
• Compatible with organic solvents to improve analyte solubility, change column selectivity, or facilitate Effective column cleaning

Dionex IonPac AS22-Fast-4µm capillary tubes use the same packing material The column provides the same performance as standard bore and microbore Dionex IonPac AS22-Fast-4µm columns. Because capillary systems operate at only 1% of the eluent flow rate of standard orifice systems, less eluent is required and less waste is produced, thus reducing operating costs.

• 4x150mm, 2x150mm analytical column
• 4x30mm, 2x30mm guard column
Shorter 150mm columns help speed up runs while smaller particles maintain higher resolution separations

Note: For simple, accurate preparation, use Dionex IonPac AS22 concentrated eluent or Dionex eluent generator (Dionex EGC 500 K2CO3 eluent tank with Dionex EPM 500 pH adjuster).
