Both the (USP) and the International Conference on Harmonization (ICH) have updated, or are in the process of updating, analytical requirements for controlling elemental impurities.

Others, such as catalysts, are intentionally added during the synthesis, while some are introduced unintentionally through interactions with processing equipment and/or container closure systems. Most importantly, it is a qualitative method that involves the reaction of metallic impurities with sulfide ions to generate a colored precipitate.Lengthy process USP began the standards-setting process in 2008.Several public meetings and USP Pharmacopeial Education courses were held to gather and share user input.The company has got approval for about 30 ANDA's and about 15 ANDA's are under pipeline. Developed, validated and transferred HPLC, GC, PSD and Dissolution methods .Maintained the records of test data in conformance with the company and regulatory policies . Reverse Phase HPLC Method Development, Waters Corporation ( March 2006 ) .
