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.
Sodium Fluoride, Reference Standard
Supplier: USP
USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.
