It is a well-known adage that “the devil is in the details.” As authoritative texts and regulatory guidelines that address the chemical characterization of medical devices usually present concepts and generalities and lack granularity, sponsors seeking to design and implement extraction studies for medical devices occasionally struggle to establish and justify critical experimental details that are scientifically sound, practical, achievable, and regulatory compliant.
This presentation provides insights into several of these critical experimental details, addressing concepts that include:
- The “It All Comes Out at Once” Paradox
- Exhaustive Extractions as a Source of Kinetic Release Data
- Predicting Exhaustive Extractions with a Minimum Number of Extraction Steps
- A Rational (?) Approach to Quantitation and Managing the AET
- Accurate versus Protective Quantitation
- What exactly is a “Semi-polar” Solvent?

He is widely published on E&L and related topics and is an active member of national and international standard setting organizations.
Extractables and Leachables on Combination Devices
Qualifying injection devices for parenteral administration requires a particular approach when designing studies for extractables and leachables. This presentation will provide an introduction to Medical Device Regulations (ISO 10993 series). It will delve into the distinct practical approaches required for medical devices in comparison to considerations for pharmaceutical packaging, especially in the context of combination products. Several case studies will highlight the critical points in study design and clarify the specific guidelines that must be considered.
Presented by Pieter Van Wouwe PhD, Senior Expert E&L at Nelson Labs

Pieter Van Wouwe obtained his Master’s degree and PhD in Bioscience Engineering from the University of Leuven in 2011. In March 2016, he started his role as a project manager at Nelson Labs. Since then, his responsibilities have included overseeing the design of extractable and leachable studies, as well as conducting scientific interpretation and reporting of analytical results. His focus has centered on extractable/leachable projects related to large volume parenteral applications, single-use systems utilized in drug product manufacturing, and infusion devices.
