Dionex™ IonPac™ AS32-Fast-4μm Analytical and Guard Columns (Thermo Scientific™)

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.

Key Features

Superior Chromatographic Performance

High capacity allows injection of complex matrices without overloading the column while maintaining excellent peak shapes for lower concentration analytes.
Ultralow hydrophobicity and reduced 150mm column length allow for fast analysis of highly polarizable anions such as perchlorate and iodide with a simple, isocratic eluent.
Quickly separate disparate concentration ratios (1:1000) of perchlorate in high sulfate matrices using simple, isocratic conditions.
Separate polythionates such as dithionate, trithionate, and tetrathionate.
Separate color additives including FD&C Yellow #5, FD&C Yellow #6, FD&C Blue #1, and FD&C Red #40 using a hydroxide gradient.

Use with a High-Pressure IC system

A high-pressure IC system, such as the Thermo Scientific™ Dionex™ ICS-6000 HPIC system or Thermo Scientific™ Dionex™ Integrion™ HPIC system is required to operate this column under standard conditions.
