The utility of adding isothermal measurement data (0K/min) to temperature rise measurement data.
Does adding isothermal measurement data affect thermal safety evaluation? Introduction of technical materials.
This document is a technical note explaining the utility of adding isothermal measurement data (0 K/min) to heating rate measurement data. The recommended heating rates for DSC are between 0.5 K/min and 8 K/min, but adding just one isothermal measurement can further improve analysis accuracy. The appropriate temperature setting for the isothermal condition can be determined from the measurement data at 0.5 to 8 K/min. Please feel free to download and take a look. [Published Data (Excerpt)] - Reaction rate curve based solely on five heating data points at 0.5 to 8 K/min - Reaction rate curve based solely on five heating data points at 0.5 to 8 K/min - Difference in activation energy based on only five heating data points and one isothermal data point - Reaction rate vs. time axis displayed under isothermal conditions *For more details, please download the PDF or feel free to contact us.

Company information
Our company works in the field of thermal safety evaluation to prevent thermal runaway accidents involving chemical substances. To achieve this, we analyze reaction kinetics parameters from thermal measurement data of a few milligrams of chemical substances and provide a measurement and analysis system that enables thermal safety evaluation when the chemical substances are scaled up to kg to 1000 kg. Additionally, we offer an evaluation system that combines isothermal microcalorimeters (IMC) for lithium-ion batteries and DSC with AKTS analysis software, allowing for comprehensive measurement of the entire battery.
