Use these shorter 150mm Thermo Scientific™ Dionex™ IonPac™ AS18-Fast columns for fast runs when monitoring inorganic anions in drinking water and wastewater samples for compliance with U.S. EPA Methods 300.0 (A) and 300.1. Dionex IonPac AS18 columns are high capacity hydroxide-selective anion-exchange columns. Having the same selectivity as the Dionex IonPac AS18 column, the shorter format significantly reduces run times of common inorganic anions and low molecular weight organic acids in diverse sample matrices including drinking water, wastewater, leachates, foods, beverages, and 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:
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.
