Simultaneous Thermal Analysis (STA) + (GC-MS) 101: Method & Applications

Simultaneous Thermal Analysis (STA) is a powerful technique that enables comprehensive thermal characterization by measuring multiple thermal responses under precise temperature control. With STA, you can capture key material events such as phase transitions, mass loss and decomposition, combustion, oxidation, and more, while building a clearer picture of how a material behaves as conditions change.

In this informative webinar, we will cover the operational principles of STA, an overview of the instrumentation, practical considerations for method setup, and how to interpret common data outputs. We will also highlight real-world STA applications across polymers, pharmaceuticals, and materials science, with an emphasis on connecting thermal events to meaningful material behavior.

This session will also introduce STA coupled with Gas Chromatography Mass Spectrometry (GCMS), a powerful combination that links thermal events to the identity of evolved gases. By pairing STA data (when mass changes occur and under what thermal conditions) with GCMS (what compounds are released), users can move beyond “what happened” to “what was produced,” improving confidence in root-cause analysis and strengthening conclusions in both R and D and quality investigations. We will discuss coupling concepts, workflow considerations, and examples where evolved gas analysis can clarify decomposition pathways, residual solvents, additives and plasticizers, contaminants, and reaction byproducts.

Additionally, the webinar will feature the Sample Observation capability of the Rigaku STA. Real-time sample visualization can make data interpretation more intuitive, add confidence when correlating signals to physical changes, and provide images that help users communicate thermal events clearly, especially when paired with complementary evolved gas identification.

Whether you are new to STA or looking to expand your capabilities with evolved gas analysis using GCMS, this webinar will provide a solid foundation in STA fundamentals and practical insights for leveraging STA plus GCMS to tell a more complete materials story.
