Waters EU - Using XP Columns to Modernize the USP Organic Impurities Analysis of Tioconazole

The United States Pharmacopeial Convention (USP) has added nearly 800 new records, mostly from 2011 and 2012, to its Food Fraud Database, increasing the size of the database by 60%. The original database contained 1,300 records, covering fraud reports issued between 1980 and 2010. The database compiles data taken from publicly available reports in both scholarly journals and general media, with key findings published in the Journal of Food Science (1).
