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.
