Launch of Heating Evolved Gas Analysis Service with Simultaneous Humidity and Oxygen Concentration Control

Toray Research Center, Inc. (TRC) has launched a Temperature Programmed Desorption Mass Spectrometry (TPD-MS) service that provides stable, simultaneous control of humidity and oxygen concentration. The behavior of gases evolved during heating is significantly influenced not only by temperature but also by environmental conditions such as humidity and oxygen levels. However, achieving stable and reproducible analysis while controlling these factors has been technically difficult due to issues like moisture affecting mass spectrometer stability and the complexity of controlling reactions in the presence of oxygen. By integrating its proprietary atmosphere control technology into TPD-MS, TRC has enabled the measurement of evolved gases under precisely controlled humidity and oxygen conditions, simulating real-world environments such as atmospheric pressure. This service allows for the identification of trace gas types and temperature ranges released when products are exposed to high-temperature conditions, which can be used to detect signs of material degradation and estimate risks to human health and the surrounding environment. This service is considered particularly useful in the energy storage materials sector, where material degradation and gas evolution behavior change significantly due to heat generated during charging/discharging and external environmental factors, directly impacting safety risks. Furthermore, it is expected to contribute to the advancement of safety design and the reduction of evaluation periods in material selection and design phases across a wide range of fields, including electronic components, composite materials, resins, and adhesives.
