• Compliance monitoring of common anions in drinking water as specified in U.S. EPA Method 300.0 (A)
• Determination of low levels of inorganic anions in complex matrices using large-loop injections
• Superior retention and quantification of fluoride, acetate, and formate
• Fast separation of the common inorganic anions in 5 min in simple matrices using 150mm column
• High efficiency, fast analysis use the 150mm column for increased sample throughput
• Compatible with organic solvents to enhance analyte solubility, modify column selectivity, or allow effective column cleanup

• Source water and drinking water, municipal and industrial wastewater
• Industrial cooling water and waste water, acid rain
• Foods and beverages, anionic counterions in pharmaceutical preparations

The shorter 150mm Dionex IonPac AS18-Fast columns produce faster runs of relatively clean matrices compared to the longer 250mm columns and are available in three formats with guard columns:

• 4x150mm standard bore AS18-Fast columns with 4x30mm guard columns
• 2x150mm microbore AS18-Fast columns with 2x30mm guard columns
• 0.4x150mm capillary AS18-Fast columns with 0.4x35mm guard columns

Capillary columns provide significantly reduced operating and waste disposal costs through eluent conservation. Packed with the same material, the Dionex IonPac AS18-Fast capillary columns provide the same performance as the standard bore and microbore counterparts. Operating costs are reduced because the capillary system operates at only 1% of the eluent flow rate of the standard bore system. Capillary columns are used with the Thermo Scientific™ Dionex™ ICS-4000 and ICS-5000+ Capillary systems.

• If you need higher resolution separations of more complex sample matrices, refer to the longer 250mm Dionex™ IonPac™ AS18 Hydroxide-Selective Anion-Exchange column
• For fastest, highest resolution separations of relatively cleaner sample matrices, refer to the small particle Dionex™ IonPac™ AS18-4µm Hydroxide-Selective Anion-Exchange column. Use of 4µm columns requires a high-pressure IC system.
