You searched for: Cationic Standards

VWR offers a wide range of certified cationic standards designed for instrument calibration in ion-exchange chromatography (IC) applications, which can be applied toward environmental or food analysis and quality control. IC is an analytical technique used for the separation and quantification of anions and cations in aqueous samples. VWR offers high-purity, well-defined reference materials ideal for low-ppm level quantification or trace analysis. Bottles of cationic standards are available for a range of elements.
