DESCRIPTION
For separation of a wide variety of polyvalent anions, including polyphosphates, polyphosphonates, and other polyvalent complexing agents, the Thermo Scientific™ Dionex™ IonPac™ AS7 anion-exchange column delivers excellent results. The column has a unique polymer packing that provides superior performance for separating ionic and polar compounds that offers high speed, high efficiency, and high loading capacity at moderate backpressures. However, the newer Dionex IonPac AS16 column is recommended for determination of polyphosphates.
