Determine trace-level concentrations of inorganic anions and low-molecular-weight organic acids in high-purity water matrices with the Thermo Scientific™ Dionex™ IonPac™ AS15 Capillary, Analytical & Guard Columns. Specifically designed for analysis of trace anions in high-purity water matrices used by the semiconductor and power generation industries, the column delivers high sensitivity and superior resolution of early-eluting anions (e.g., fluoride, glycolate, acetate, and formate). The column is optimized for selective at an operating temperature of 30˚C, and it is ideal for use with large-loop injections.
Dionex IonPac AS15-5µm (3x150mm) column for high efficiency, fast analysis (15 min)
Dionex IonPac AS15-9µm (2x250mm, 4x250mm, and 0.4x250mm) columns for higher-capacity applications
Dionex IonPac AS15 capillary column (0.4x250mm) delivers the performance of the standard bore version but requires only 1% of the eluent flow rate, which helps reduce operating costs
For Best Performance
Use the Thermo Scientific™ Dionex™ IonPac™ AC15 Concentrator column for ultratrace (part per trillion) analyses
Use a Dionex eluent generator for simplified eluent preparation
Use the Thermo Scientific™ Dionex™ Anion Self-Regenerating Suppressor (ASRS™ 300) or the Thermo Scientific™ Dionex™ Anion Capillary Electrolytic Suppressor (ACES™ 300) with the Dionex IonPac AS15 column for eluent suppression
