Anionic Standards
Avantor offers a wide range of certified anionic 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. Avantor offers high-purity, well-defined reference materials ideal for low-ppm level quantification or trace analysis. Bottles of anionic standards are available for a range of elements.
