The IonPac® AS15 is a high-capacity, hydroxide-selective anion-exchange column designed for the determination of trace-level concentrations of inorganic anions and low molecular weight organic acids, including fluoride, glycolate, acetate, formate, chloride, nitrite, carbonate, sulfate, oxalate, bromide, nitrate, and phosphate in high-purity water matrices encountered in the semiconductor and power generation industries. The IonPac AS15 column offers excellent retention of fluoride from the water dip and uses a simple hydroxide eluent easily supplied by the Eluent Generator (EG).

The IonPac AS15 column is available in formats from 0.4 to 4 mm, allowing use of capillary to analytical flow rates, and supporting advanced IC × IC applications.
