DESCRIPTION
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.
