Thermo Fisher, 303152, Dionex™ IonPac™ AS32-Fast-4μm Analytical and Guard Columns

Guard Column, 4 mm, 30 mm, 1.0 mL/min. Resolve polythionates, persulfate, polysulfonated aromatics, and aromatic dyes and pigments with the Thermo Scientific™ Dionex™ IonPac™ AS32-Fast-4μm column. The unique selectivity of the Dionex IonPac AS32-Fast-4μm column allows it to resolve trace amounts of perchlorate in matrices containing high levels of chloride and sulfate within ten minutes using simple, isocratic conditions. Compared to similar anion-exchange columns packed with 7-9μm resin particles, Dionex IonPac AS32-Fast-4μm columns produce more efficient peaks, resulting in more accurate integration and more reliable results.
