Compliance with USP and ICH
In an effort to improve and modernize the USP General Chapter for Heavy Metals <231>, the USP harmonized with ICH and proposed the addition of two new General Chapters and a Supplemental General Chapter:
- <233> Elemental Impurities – Procedure
- <232> Elemental Impurities – Limits
- <2232> Elemental Contaminants in Dietary Supplements
Our methods comply with the new chapters and provide better precision and accuracy than those that could be achieved with USP <231>.
