Dionex™ IonPac™ AS25 IC Columns

Separate multivalent and polarizable anions in 25 minutes without solvents using the Thermo Scientific™ Dionex IonPac AS25 column. This high-capacity, hydroxide-selective, anion-exchange column is ideal for the determination of sulfur species in complex matrices such as food and beverage samples as well as wastewater effluents from the industrial, chemical, and petrochemical industries. This column delivers fast, simple separation of polarizable anions, including thiosulfate, iodide, thiocyanate, and perchlorate. For the best peak shape of polarizable anions, use the Thermo Scientific™ Dionex™ IonPac™ AS16 column or the Thermo Scientific™ Dionex™ IonPac AS20 column.

Recommended for Fast Separation of Multivalent Anions in Diverse Sample Matrices

• Municipal wastewater
• Food processing samples
• Paper and pulp effluents
• Refinery waste products
• Industrial wastewaters
• Industrial scrubber solutions
• Geothermal power plant samples

Superior Chromatographic Performance

• High capacity: 350μeq per column (4x250mm)
• Ideal for polyvalent anions, including polysulfates, polyphosphates and polycarboxylates
• Ultralow hydrophobicity allows fast analysis of polarizable anions
• Low background signal and enhanced analyte sensitivity with the Thermo Scientific™ Dionex™ Anion Self-Regenerating Suppressor (ASRS™ 300) and a Reagent-Free™ (RFIC™) system
• Compatible with organic solvents to enhance analyte solubility, modify column selectivity, and effectively clean the column

Available in Multiple Formats

The Dionex IonPac AS25 column is available in formats supporting flow rates from 0.25 to 3mL/min. The microbore format requires less eluent consumption, thereby reducing operating costs.
