Dionex IonPac AS22 Analytical Column - Fast Isocratic Anion Separation

The Dionex IonPac AS22 is an anion-exchange analytical column optimized for fast, isocratic separation of common inorganic anions using carbonate/bicarbonate eluent. This column delivers baseline resolution of 7 common anions (fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate) in under 15 minutes.

Key Specifications:

• Manufacturer: Thermo Scientific (Dionex)
• Column Type: Anion-exchange analytical column
• Eluent: 4.5 mM Na₂CO₃ / 1.4 mM NaHCO₃ (isocratic)
• Format: 4 x 250 mm (analytical)
• Latex: Alkanol quaternary ammonium
• Part Number: 088486

Why Choose the IonPac AS22?

The AS22 is designed for laboratories that need a simple, reliable IC method without eluent generators. Using a manually prepared carbonate/bicarbonate eluent, the AS22 delivers fast separations with isocratic elution — no gradient programming needed.

This makes the AS22 ideal for routine water quality laboratories, environmental compliance testing, and any application where simplicity and speed are priorities. The column provides excellent selectivity for common anions with minimal method development.

Applications:

• Drinking water quality monitoring (EPA 300.0 / 300.1)
• Wastewater compliance testing
• Power plant boiler water chemistry
• Soil and groundwater environmental analysis
• Food and beverage quality control
• Routine QC anion screening

Recommended System Configuration:
