USP 232 Elemental Impurities
The United States Pharmacopeia (USP) and the International Council for Harmonisation (ICH) set limits for elemental impurities in drug products, detailed in USP General Chapter 232 and ICH Guideline for Elemental Impurities Q3D.
We provide USP 232 reference standards based on oral permitted daily exposures along with an internal standard. Additionally available are High and Low Level multi-element calibration standards, allowing for quantitative analysis through custom applications.
