Modernizing Trace Metal Testing: USP 232/233 at MAS, LLC

In the ever-evolving field of pharmaceuticals, ensuring the purity and safety of drug products is paramount. At Materials Analytical Services, LLC (MAS), we are at the forefront of this mission, leveraging cutting-edge technologies and methodologies to provide comprehensive trace metal testing. Located at 3945 Lakefield Ct, Suwanee, GA 30024, MAS is proud to announce the verification of USP 233 by ICP-MS, ready to serve the diverse needs of the pharmaceutical industry.

The Transition from USP 231 to USP 232/233

For over a century, the United States Pharmacopeia (USP) 231 was the standard for heavy metal testing in pharmaceutical samples. However, due to its limitations, it has now been replaced by USP 232 Elemental Impurities Limits and USP 233 Elemental Impurities Procedures. This transition marks a significant advancement in the industry, mandating the use of USP 233 by 2018 to enhance the accuracy and reliability of impurity testing. Learn more in our pharmaceutical testing page.

Benefits of Modern Testing Methods

Contact with manufacturing equipment, residual catalysts, and raw materials can introduce elemental impurities into drug products. The implementation of USP 232/233 redefines the testing process for these impurities. Procedures 1 and 2, integral to these standards, offer detectability, repeatability, and specificity that surpass the subjective colorimetric tests used in USP 231.

Advanced Validation Techniques

USP 233 requires rigorous method validation, whether as a limit test or a quantitative test. Limit tests focus on precision, while quantitative validation demands accuracy at 50%, 100%, and 150%. Techniques such as ICP-OES and ICP-MS provide superior analytical capabilities, with ICP-MS measuring mass fragments to a higher degree of precision.

The Need for Change

The presence of impurities can cause toxicity, unwanted side effects, and impact drug stability. USP 232/233 address these issues by providing a modernized approach to testing. These new methods enable pharmaceutical labs worldwide to update their techniques and instrumentation, ensuring complete digestion and retention of volatile elements through methods like closed vessel microwave digestion.
