Thermo Fisher, 303162, Dionex™ IonPac™ AS30 Analytical and Guard IC Columns

Guard Column, 2 mm, 50 mm, 0.38 to 0.50 mL/min. Achieve high resolution separations of trace oxyhalides and inorganic anions in drinking water with Thermo Scientific™ Dionex™ IonPac™ AS30 columns. The column selectivity has been optimized for trace level analysis of bromate in drinking water preserved with ethylenediamine (EDA). EDA is used as a preservative in some drinking water samples and can cause interference with early eluting peaks. The high capacity of this hydroxide-selective anion-exchange column allows large loop injections for trace analysis (μg/L) without sample pre-treatment or preconcentration.
