ARE YOU READY FOR THE REPLACEMENT OF USP <231> HEAVY METALS?

Alcami Wants You to Stay in Compliance.

The U.S. Pharmacopeia (USP) is retiring the existing wet chemistry heavy metals methods outlined in USP General Chapter <231> with an instrument-based approach on January 1, 2018. Though the existing wet chemistry methods have been in effect for nearly 100 years, the methods are non-specific and frequently fail to detect or underestimate the presence of some toxic elements that are potentially present in pharmaceutical ingredient. 

The USP heavily supports Inductively Coupled Plasma Mass Spectrometry (ICP-MS) as the replacement technique to screen and/or accurately quantitate the presence of any metals of interest.  USP General Chapters <232> and <233> Elemental Impurities Limits and Procedures is the expected norm for evaluation and are already accessible monographs for analysis.
