Overview

Materials and substances such as plastics, greases, oils and fats are easily investigated by thermal analysis techniques. Oxidation stability can be characterized by oxidation induction time (OIT) or oxidation onset temperature (OOT). The OIT of a material is measured in an oxygen atmosphere at a particular isothermal temperature whereas the more rapid OOT is determined in a dynamic measurement in oxygen.

Join this webinar to learn about OIT and OOT methods, and different industries and applications for each. Attendees will learn about different instruments for measurement and why thermal analysis is useful for organic materials.

Key Takeaways

  • Understand why oxidation induction studies are useful
  • Learn the difference of OIT versus OOT methods
  • Discover why pressure can provide even better information
  • See tips and hints regarding ASTM OIT standards

Speaker

Dr. Angela Hammer, Senior Applications Chemist, Thermal Analysis, Mettler-Toledo, Analytical

Dr. Angela Hammer studied chemistry. During her dissertation at the Institute of Organic Chemistry at the Swiss Federal Institute of Technology in Z├╝rich, Switzerland, she specialized in the development of immobilized components in ion-selective electrodes based on polyurethane membranes.

She then joined Sika Technology AG in Zurich Switzerland, as an analytical chemist. In 2007 she joined Mettler-Toledo AG and has worked there since as application specialist for thermal analysis. In her present position she uses, teaches and supports DSC, TGA, TMA and DMA instruments at the Mettler-Toledo AG head office in Switzerland.
