Notice of Revision to General Chapter Heavy Metals <231> Method II

June 14, 2005

In response to comments from industry, USP is reverting back to the Heavy Metals text that appeared in USP 28–NF 23 page 2300 for Heavy Metals Method II. The USP 28–NF 23 test has been used in industry for some time. The search continues for a more robust and practical method. This change will appear in the Third Interim Revision Announcement to USP 29–NF 24 which will be published in Pharmacopeial Forum 32(3) and will become official on June 1, 2006.

Should you have any questions, please contact Kahkashan Zaidi, Ph.D., Senior Scientist, General Chapters (1+301-816-8269 or ).
