• Chemical Composition Analysis: Using FTIR to identify polymer types and chemical bonds, providing a unique “fingerprint” of materials. FTIR analysis shines infrared light on a sample and measures how the material absorbs different wavelengths, allowing rapid identification and verification of polymers, additives, or contaminants. We also utilize chromatography and mass spectrometry (e.g. GC-MS) for detecting and quantifying organic compounds (such as additives, leachables or residual solvents) in device materials. For metals and inorganics, analytical instruments like X-ray fluorescence (XRF) and Atomic Spectroscopy determine elemental composition and detect trace heavy metals.
• Surface and Structural Characterization: High-resolution Microscopy techniques reveal the morphology and microstructure of device materials. Scanning Electron Microscopy (SEM) allows us to examine surface topography and microscopic features at magnifications up to 100,000×. SEM is indispensable for inspecting coatings, surface textures, and micro-defects (e.g. cracks or wear patterns) on implants or device components. Coupled with Energy-Dispersive X-ray Spectroscopy (EDS), SEM can also pinpoint elemental composition at failure sites or inclusions. For surface chemistry and thin films (such as stent coatings or oxide layers), we offer XPS (X-ray Photoelectron Spectroscopy) to identify contaminants and chemical states on device surfaces. These surface analysis techniques ensure that material interfaces and coatings (critical for implants, catheters, etc.) meet design specifications and are free of harmful contaminants.
• Thermal Analysis: We characterize thermal properties using DSC and TGA. DSC measures how a material’s heat flow changes with temperature, revealing melting points, crystallinity levels, glass transition temperatures (Tg) and phase transitions. This is especially important for polymers and shape-memory alloys (like Nitinol stents) to ensure they function in the intended temperature range. For example, DSC is commonly used in polymer testing to verify a plastic’s thermal stability and transition temperatures. TGA complements this by measuring weight changes upon heating, identifying decomposition temperatures or moisture content. These tests confirm that device materials will remain stable and not degrade under expected storage and use conditions.
• Mechanical Testing: Ensuring that a medical device can withstand real-world forces is paramount. We perform extensive mechanical tests to measure properties like elongation, tensile strength, compression resistance, flexural strength, hardness, and fatigue durability. Using precision mechanical testing systems (e.g. Instron machines), we evaluate stress-strain behavior (tension, compression, shear, flexure) to determine a material’s elasticity, yield strength, and ultimate strength. Hardness testing (durometer or micro indentation) assesses a material’s resistance to surface deformation. We also conduct fatigue testing (cyclic loading) for implants and components that experience repeated stress (such as stents, orthopedic implants or catheter tubing) to ensure long-term durability. These mechanical evaluations are performed per relevant ASTM/ISO standards to demonstrate that the device meets all mechanical performance requirements set by regulators. In short, mechanical testing is utmost importance to confirm safety and reliability of medical devices in use.

By leveraging comprehensive techniques (SEM, FTIR, DSC, mechanical testing, and more) for material characterization, we enable medical device organizations to fully understand their product’s material profile. This ensures each device is built on a solid foundation of quality, compliance, and performance.
