Lesson Summary
Professor Janne Jännis, renowned for his expertise at the Department of Chemistry of University of Eastern Finland, delivered a lesson on high-resolution mass spectrometry characterization of plastics. The lesson covered:
- The distinction between polymers and plastics, physical and chemical properties of polymers, and the chemistry of plastics.
- The use of mass spectrometry in analyzing polymers and plastics with techniques like electrospray ionization and matrix-assisted laser desorption/ionization.
- The importance of high mass resolution in analyzing complex plastic samples and identifying polymer characteristics.
- The role of mass spectrometry in identifying polymer identity, heterogeneity, branching, molecular weight, and end-group chemistry.
- The significance of flame retardants in plastics and common classes of brominated flame retardants used.
