Dionex IonPac AS15 阴离子交换柱

For Trace-Level Concentrations of Inorganic Anions and Low-Molecular Weight Organic Acids

The IonPac^? AS15 column was designed specifically for analysis of trace anions in high-purity water matrices, for the semiconductor and power generation industries. Its high capacity and selectivity enable the determination of trace-level concentrations of inorganic anions and low-molecular-weight organic acids in high-purity water matrices. The new IonPac AS15 Capillary Column is packed with the same material as the equivalent standard bore version (providing the same performance as a 4 mm column) but requires only 1/100th the eluent flow rate. The capillary format provides the advantage of significantly reduced eluent consumption, which helps reduce operating costs.

• AS15-5μm (3 × 150 mm) column for high efficiency, fast analysis (15 min)

• AS15-9μm (2 × 250, 4 × 250 mm, and 0.4 × 250 mm) columns for higher-capacity applications

• Column selectivity optimized for 30 °C operating temperature

• Superior resolution of early-eluting anions (fluoride, glycolate, acetate, and formate)

This column is ideal for use with large-loop injections. Use the AC15 concentration column for ultratrace (ppt) analyses. Use with eluent generation for simplified eluent preparation. Use the Anion Self-Regenerating Suppressor^? (ASRS^? 300) or the Anion Capillary Electrolytic Suppressor (ACES^? 300) with the AS15 column for eluent suppression.
