Chemical Characterization to Ensure Product Safety

Utilize our comprehensive approach towards chemical characterization to identify extractables and leachables. These compounds may be organic or inorganic in nature, typically from devices which contain additives. These additives include materials such as lubricants, accelerators, monomers, and high molecular weight oligomers from incomplete polymerization, and residual solvents. Extractables may also be formed due to temperature, absorption, hydrolysis, oxidation, corrosion, or dissolution events. Agents used the manufacturing process itself, such as mole release, anti-static, and anti-stick agents, also may contribute.
Conducting this testing helps identify potential biological risks to the end user. Extractable and leachable testing is particularly relevant to medical device packaging, as leachables in devices may compromise patient safety.

Analyze Extractable & Leachable Compounds

When we conduct chemical characterization studies for extractables, our approach is to subject your device to worse-case conditions. We then characterize the constituents extracted from the component under these exaggerated conditions. Extraction conditions, such as solvents, extraction time, and temperature, are chosen based on guidance, such as ISO 10993-18. Our experienced team then analyzes and semi-quantitates these extracts using the following techniques and instrumentation:

  • Ultra Performance Liquid Chromatography-Photo Diode Array-Time of Flight Mass Spectrometry (UPLC-PDA-QTOF-MS) to identify non-volatile organic compounds.
  • Direct Injection Gas Chromatography-Mass Spectrometry (DI-GC-MS) to identify semi-volatile organic compounds.
  • Static Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) to identify volatile organic compounds.
  • Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) or Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) to identify elemental impurities.
  • Non-Volatile Residue (NVR) analysis to establish exhaustive extraction conditions.

Once extractables are evaluated, we often develop a targeted leachables study to specifically quantitate compounds of concern that were identified in the extractables analysis. The methods we use to quantify leachables are validated and used in long term stability studies. Additionally, our team performs simulation studies to determine potential leachables under accelerated conditions.
