Chemical Characterization
Under ISO 10993-18:2020
— What Device Makers
Get Wrong
Incomplete strategies, poor study design and inadequate risk assessments are the most common reasons chemical characterization fails to satisfy modern regulators.
Chemical characterization has become one of the most important components of modern medical device safety evaluation. Under ISO 10993-18:2020, regulators now expect manufacturers to generate detailed scientific evidence regarding the chemical composition, extractables, leachables and toxicological risks associated with medical device materials.
However, many device manufacturers still underestimate the complexity of chemical characterization studies. As regulatory expectations continue to evolve, incomplete strategies, poor study design and inadequate risk assessments are becoming common reasons for approval delays and regulatory deficiencies.
At Accuprec Research Labs Pvt. Ltd., we help medical device manufacturers develop scientifically robust and regulator-ready chemical characterization programs aligned with ISO 10993-18:2020 and global regulatory expectations.
Why Chemical Characterization Is Critical
Chemical characterization provides essential information about the materials used in medical devices and identifies compounds that may migrate from the device during clinical use. Modern regulators increasingly rely on chemical characterization because it provides a scientific foundation for understanding device-material interactions and potential patient exposure risks.
Without comprehensive chemical characterization data, manufacturers may face significant challenges during regulatory review.
These studies support:
- Biological safety evaluation
- Toxicological risk assessment
- Material qualification
- Regulatory compliance
- Biocompatibility planning
- Patient safety assurance
Common Mistakes Device Makers Make
One of the biggest mistakes manufacturers make is treating chemical characterization as a routine analytical activity instead of a strategic regulatory requirement.
- Incomplete extractables and leachables studies
- Poorly defined analytical thresholds
- Inadequate method sensitivity
- Weak toxicological assessments
- Insufficient material information
- Lack of regulatory-focused study planning
- Failure to align with ISO 10993-18:2020 expectations
In many cases, companies generate analytical data without a clear toxicological interpretation strategy — which leads to regulator concerns and additional information requests.
The Importance of Extractables & Leachables Studies
Extractables and leachables evaluations are central to chemical characterization programs.
Extractables Studies
Identify chemicals that can potentially migrate from device materials under aggressive laboratory extraction conditions — simulating worst-case scenarios.
Leachables Studies
Assess compounds actually released during real clinical use conditions — representing genuine patient exposure scenarios.
These evaluations help determine:
- Patient exposure risks
- Material compatibility
- Toxicological safety margins
- Manufacturing consistency
- Long-term device safety
Without properly designed extractables and leachables studies, manufacturers may fail to adequately characterize device-related risks.
Advanced Analytical Capabilities Matter
Reliable chemical characterization requires highly sensitive and scientifically validated analytical technologies. At Accuprec, our scientific teams also ensure that analytical methods are appropriately validated and aligned with regulatory expectations.
Our laboratories support advanced characterization studies using:
GC-MS Analysis
Gas chromatography-mass spectrometry for volatile and semi-volatile organic compound identification and quantification.
LC-MS/MS Analysis
Liquid chromatography tandem mass spectrometry for non-volatile and trace-level compound detection with high sensitivity.
ICP-MS Analysis
Inductively coupled plasma mass spectrometry for ultra-trace elemental impurity and metal leachables analysis.
Spectroscopic Analysis
FTIR, UV-Vis and Raman spectroscopy for structural identification and material characterization support.
Chromatographic Profiling
Comprehensive organic and inorganic compound profiling for complete chemical characterization packages.
Regulatory-Focused Risk Assessment
Generating analytical data alone is not sufficient. Modern regulators expect manufacturers to provide toxicological interpretation and scientifically justified risk assessments. This integrated approach strengthens regulatory submissions and improves reviewer confidence.
At Accuprec, we help clients develop:
Toxicological Risk Evaluations
Scientific assessment of identified chemical compounds against established toxicological safety thresholds.
Safety Threshold & Exposure Calculations
Quantitative patient exposure assessments with margin of safety calculations per ISO 10993-17.
Regulatory Justification Reports
Scientifically written documentation addressing regulator expectations and supporting approval submissions.
Material Safety Evaluations
Comprehensive device material qualification reports supporting biological evaluation strategies.
Why ISO 10993-18:2020 Requires a Strategic Approach
The updated ISO 10993-18:2020 standard emphasizes risk-based evaluation and deeper scientific understanding of device materials. Companies that fail to adopt a strategic and scientifically justified approach often encounter regulatory delays and increased approval risks.
Manufacturers are now expected to:
Understand Material Composition
Thoroughly document and evaluate all materials, components and processing aids used in device manufacturing.
Characterize E&L Compounds
Identify and quantify all extractable and leachable compounds using orthogonal analytical techniques.
Establish Analytical Thresholds
Define scientifically justified analytical evaluation thresholds (AET) for identification and reporting.
Integrate Into Biological Evaluation
Connect chemical characterization data directly into the biological evaluation and risk assessment strategy.
