ISO 10993-18 Semi-Volatile Organic Compounds Analysis by GC-MS
The ISO 10993-18 standard is a pivotal guideline for ensuring the safety of medical devices used in healthcare environments. This section focuses specifically on the analysis of semi-volatile organic compounds (SVOCs) within medical devices, employing gas chromatography-mass spectrometry (GC-MS). SVOCs are chemicals that have low boiling points and can migrate from the surface of a device into contact with biological tissues or fluids. The rigorous testing outlined in ISO 10993-18 is essential to minimize potential risks associated with these compounds.
Our laboratory employs advanced GC-MS technology to conduct precise and reliable analyses, ensuring that all SVOCs are identified and quantified according to the standard's requirements. This process involves a series of steps: sample preparation, injection into the gas chromatograph, separation based on volatility, and finally identification through mass spectrometry. The resulting data provides critical insights into the composition of SVOCs present in medical devices, aiding in regulatory compliance and enhancing patient safety.
The importance of this analysis cannot be overstated. SVOCs can migrate from various components of a medical device such as adhesives, coatings, or packaging materials. These compounds may potentially leach out into the body during use, posing risks to patients' health. By adhering strictly to ISO 10993-18, our laboratory helps manufacturers and developers ensure that their products meet stringent safety standards.
The standard specifies a range of SVOCs that must be analyzed, including but not limited to phenolic compounds, aliphatic hydrocarbons, aromatic hydrocarbons, and halogenated hydrocarbons. The choice of compounds depends on the specific type of medical device being tested. For instance, devices with rubber or plastic components may require a different set of SVOCs compared to those made from metals.
Our GC-MS system is calibrated using certified reference materials (CRMs) to ensure accurate and reproducible results. The laboratory personnel undergo rigorous training to operate the equipment and interpret the data accurately. This expertise, combined with state-of-the-art instrumentation, guarantees that each analysis meets or exceeds ISO 10993-18 requirements.
Once the GC-MS analysis is complete, a comprehensive report is generated detailing all detected SVOCs along with their respective concentrations. This information allows manufacturers to make informed decisions regarding material selection and process optimization. Additionally, it provides regulatory bodies with transparent data supporting compliance efforts.
