Reaction onset temperature
WebAug 21, 2024 · Three variations are commonly employed: Dynamic TGA - Temperature continues to increase over time as mass is recorded. This allows simulataneous identification of how much gas is removed and the temperature at which it occurs. Static TGA - Temperature is held constant as the mass is measured. WebAug 22, 2016 · By contrast, reaction onset temperature is associated with a chemical reaction with negligible self-heating involved. This occurs for systems with very large surface-to-volume ratios such that the temperatures of the system and its surroundings remain nearly equal.
