Medical Device Extractable VOC Testing
The medical device industry is subject to stringent regulations aimed at ensuring product safety and efficacy. One critical aspect of this regulation involves the assessment of extractable volatile organic compounds (VOCs) from materials used in medical devices.
Volatile Organic Compounds, as defined by international standards such as ISO 17025, are chemical substances that have a high vapor pressure and low boiling point. These compounds can leach into the environment or be released during use of the device, potentially posing risks to patients, healthcare workers, and the general public.
Extractable VOC testing plays a pivotal role in ensuring medical devices meet regulatory requirements such as those specified by the Food and Drug Administration (FDA) and European Union Medical Device Regulation (EU MDR). The process involves simulating real-world conditions under which materials may come into contact with bodily fluids or other environments to identify any potential leachates.
Our laboratory employs state-of-the-art equipment, including high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and Fourier transform infrared spectroscopy (FTIR) for precise detection of VOCs. This enables us to provide accurate and reliable data that can inform product development decisions.
The testing procedure typically begins with sample preparation, which involves dissolving the device material in a suitable solvent under controlled conditions. The extract is then analyzed using advanced analytical techniques mentioned above to identify all detectable VOCs. Results are reported according to relevant standards like ISO 10993-18:2017.
Our team of experts ensures that each step adheres strictly to best practices outlined in these guidelines, thereby providing clients with confidence in the integrity and safety of their products. By conducting thorough extractable VOC testing early in the design phase, manufacturers can mitigate risks associated with unintended exposure to harmful substances during clinical trials or post-market use.
This service is particularly beneficial for companies developing novel materials or devices that incorporate new technologies where traditional methods may not suffice. Early identification of problematic compounds allows for corrective actions before costly rework or recalls become necessary.
