Chemical Characterization

Chemical Characterization

kimyasal karakterizasyon


Chemical characterization of materials is part of the overall biological safety of a medical device that can be applied in the identification of materials or the qualitative and quantitative analysis of chemicals contained in finished medical devices.
Through chemical characterization, some tests may be exempt from biocompatibility tests, such as mutagenicity, subchronic systemic toxicity, chronic toxicity, long-term implantation.

Chemical characterization processes of medical device materials;
• Determination of medical device production materials
• Characterization of production materials through qualitative and quantitative chemical composition
• Characterization of production materials arising during the production process. Medical device characterization for chemical substances (Excipients used in production, process contaminants, sterilization residues)
• Estimation of the probability of release of chemical substances from medical devices or production materials under clinical use conditions
• Estimation of the release of chemical substances from medical devices or production materials under clinical use conditions. determination of chemical substances

• Comprehensive Extraction
• FTIR test for Non-Volatile Residues or Extracts
• GC-MS test for Volatile and Semi-Volatile Organic Extracts
• ICP-MS test for Inorganic and Heavy Metal Extracts
• LC-MS test for Non-Volatile Organic Extracts
• UV-Vis spectrophotometry to evaluate colorant
• Viscosity, pH
