Dionex™ IonPac™ AS29-Fast-4μm Analytical and Guard IC Columns

Analyze inorganic anions in high ionic strength matrices using Thermo Scientific™ Dionex™ AS29-Fast-4μm ion chromatography (IC) columns. Specifically designed to handle high ionic strength samples, Dionex IonPac AS29-Fast-4μm columns can easily separate the common inorganic anions in less than 10 minutes and can tolerate samples with high or low pH without requiring any pretreatment. They are ideal for analzying drinking water, wastewater, process streams, and scrubber solutions. Use with the Dionex AS29 Eluent Concentrate for fast, convenient, and reliable eluent preparation.

• Achieve fast, isocratic separation of common inorganic anions in less than 10 minutes.
• Analyze high ionic strength samples without compromising the separation of other analytes.
• Excellent resolution of carbonate away from the common inorganic anions.
• Robust stationary phase can tolerate acidic or basic samples without the need for pretreatment.
• Similar peak efficiency to Dionex IonPac AS22-Fast-4μm column with the same elution order.
• Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components.
• Use with Dionex AS29 Eluent Concentrate for simple and accurate eluent preparation.

Higher resolution is achieved through the use of smaller resin particles, which produce a column backpressure over 3000 psi at the standard flow rates. A high-pressure IC system, such as the Thermo Scientific™ Dionex™ ICS-5000⁺ HPIC™ system or Thermo Scientific™ Dionex™ Integrion™ HPIC system is required to operate this column under standard conditions.
