Dionex IonPac AS11-HC - High-Capacity Anion-Exchange Column for Ion Chromatography

The Dionex IonPac AS11-HC is a high-capacity anion-exchange column specifically designed to resolve a large number of inorganic anions and organic acid anions from a single sample injection using hydroxide gradient elution. This is one of the most versatile anion columns in the Dionex IC portfolio.

Key Specifications:

• Manufacturer: Thermo Scientific (Dionex)
• Column Type: Anion-exchange, high capacity
• Substrate: Ethylvinylbenzene/divinylbenzene (EVB/DVB)
• Latex: Alkanol quaternary ammonium
• Format: Available in 4 mm, 2 mm, and 0.4 mm (capillary)
• Max Pressure: 4000 psi (275 bar)
• Solvent Compatibility: pH 0–14, 0–100% HPLC solvents
• Part Number: 052961

Why Choose the IonPac AS11-HC?

The AS11-HC column can resolve 30+ anions in a single gradient run — from fast-eluting monovalent anions like fluoride and chloride to strongly retained polyvalent species like phosphate, sulfate, and citrate. The high capacity of this column allows higher concentration sample injections without peak broadening or column overloading.

The column is 100% HPLC solvent compatible, enabling organic solvent gradients to modify selectivity for closely eluting peaks. Combined with the Dionex EGC 500 KOH eluent generator, hydroxide gradients deliver ultra-low baseline noise and excellent retention time reproducibility.

Applications:

• Chemical wastewater effluent analysis
• Fermentation broth organic acid profiling
• Drinking water compliance testing (EPA 300.1)
• Semiconductor and electronics industry ultra-pure water analysis
• Pulp and paper process chemistry
• Food and beverage organic acid screening

Recommended System Configuration:

• Guard Column: IonPac AG11-HC
• Suppressor: ADRS 600 (4 mm) or AERS 500e (2 mm)
• Eluent Generator: EGC 500 KOH
• Detection: Suppressed conductivity
