How to Avoid Chemical Characterization Pitfalls in Medical Devices

June 30, 2026

1:00 pm ET

Robert Mueller and Taryn Meade Brow

Medical device chemical characterization testing per ISO 10993-18 is often the leading source of delay, cost overrun, and regulatory questions in a manufacturer’s biocompatibility program. Problematic study outcomes tend to be associated with a few recurring issues, with most difficulties arising not from the analytical chemistry itself, but rather from key decisions made throughout the process.

 

This 60-minute webinar will discuss real-world case studies that encountered testing challenges. The program will present solutions that highlight the importance of extractable study design, cross-functional integration with toxicologists, clinical use considerations, and regulatory alignment to optimize testing outcomes and reduce the potential need for retesting.

 

Case study topics include:

  • Overly aggressive extractable studies: problematic outcomes from strictly following the ISO standard as well as reasonable alternatives
  • Simulated use study considerations: what constitutes a clinically relevant worst case, and how to refine the testing and assessment approach
  • Challenges with testing of degradable/resorbable devices and alternative strategies to consider
  • Cross functional evaluation planning for an integrated risk narrative

 

An audience Q&A session will follow the technical presentation.

Robert Mueller

Sr. Expert Consultant, Toxicologist, Nelson Labs

Robert Mueller has 8 years of experience working in the medical device industry. He has developed a unique perspective on testing from working for both a contract research organization and a medical device manufacturer. During his time with the medical device manufacturer, he planned and managed the execution of biological testing, chemical characterization, and wrote toxicological risk assessments for both MDR and 510(k) submissions. He is an ISO 10993-18 subject matter expert and as such he has designed custom studies for a broad range of medical devices to meet the biocompatibility requirements outlined in ISO 10993. He has provided all levels of regulatory support to a wide range of medical device companies. His expertise includes developing and qualifying analytical methods as well as conducting analytical data reviews. He has also authored regulatory body submissions and deficiency responses. Robert is currently a toxicologist at Nelson Labs.
