columns IonPac AS Anion-Exchange Column The IonPac AS is a carbonate based anion-exchange column designed for the determination of inorganic anions and low-molecular-weight organic acids including fluoride, acetate, chloride, nitrite, bromide, nitrate, phosphate, and sulfate. The AS column is used with isocratic carbonate/bicarbonate eluents and suppressed conductivity detection. The AS column can be used in combination with Dionex Eluent Generators and the Electrolytic ph Modifier (EPM), which automatically produce potassium carbonate/bicarbonate eluents from water. The IonPac AS-Fast column is ideal for fast IC using eluent generation or eluent regeneration. Column Performance The IonPac AS column meets the performance requirements specfied in U.S. Environmental Protection Agency (EPA) Method 00.0 (A). The common inorganic anions are easily separated in a variety of sample matrices, including drinking water, wastewater, process streams, and scrubber solutions. The AS selectivity provides excellent retention of fluoride from the water dip and resolution of fluoride, acetate, and formate. Solvent compatibility permits easy column cleanup after the analysis of samples with hydrophobic components. Fast IC The IonPac AS-Fast is ideal for Fast IC as it is designed to have sufficient capacity to maintain resolution even in a short column format. Fast separations are achieved on any Dionex system at higher flow rates. In a short column format, backpressures produced at higher flow rates are reduced while allowing overall shorter run times. This allows for the determination of anions with high resolution even in drinking, surface, groundwater, and wastewater matrices in under min. Laboratories can achieve higher productivity and increased throughput. Passion. Power. Productivity.

High Efficiency Particle Structure The IonPac AS column was developed using a unique polymer bonding technology. The stationary phase consists of a novel hyper-branched anion-exchange condensation polymer, electrostatically attached to the surface of a wide-pore polymeric substrate. The substrate is surface-sulfonated in exactly the same manner as is common in Dionex latex coated anion-exchange materials. However, in this anionexchange resin, alternating treatments of epoxy monomer and amines produce a coating which is grown directly off the substrate surface as illustrated in Figure. Resin capacity is controlled through the number of alternating coating cycles. The AS mm uses a high-capacity resin (0 µeq/column) with optimized selectivity for the common inorganic anions in a variety of sample matrices. Isocratic Separation of Common Inorganic Anions The AS provides excellent separation of fluoride, chloride, nitrite, bromide, nitrate, phosphate and sulfate using an isocratic carbonate/bicarbonate eluent and suppressed conductivity detection.

Fast IC The IonPac AS-Fast column is suitable for separations requiring higher flow rates for the fast analysis of inorganic anions in simple sample matrices as shown in Figure. The IonPac AS- Fast column ( 0 mm) was operated with the same eluent at. and.0 ml/min. Using a higher flow rate in a shorter column format, the overall run time was reduced to. min with optimal resolution of the common inorganic anions. The use of an AS-Fast 0 mm column format allows greater linear velocities and reduced eluent consumption compared to a mm format. Figure shows the excellent resolution for the common inorganic anions in less than min.

The IonPac AS column is also ideal for the determination of anions in food and beverage samples containing high concentrations of carbonate. Carbonated bottled water contains up to 00 mg/l (ppm) of carbonate. The unique selectivity of the AS column positions carbonate well away from the common inorganic anions and does not interfere with quantification of the analytes of interest. Figure 8 shows the determination of inorganic anions in carbonated water using the AS column. The AS column can be used to evaluate the mass balance of drugs and synthetic peptide preparations. Figure 9 illustrates the use of the AS column to determine the anionic counterion amount and type.
