TGA Analysis for Thermal Stability Assessment

Thermogravimetric Analysis (TGA) measures how a material’s weight changes with controlled temperature. Here’s how it works:

1. Sample Prep: Material is weighed and placed in a crucible.
2. Temperature Program: Controlled heating with pauses.
3. Weight Monitoring: Continuous measurement.
4. Data Analysis: Records onset temperatures, weight loss percentages, and curves.
5. Interpretation: Reveals thermal stability, composition insights, and decomposition stages.
6. Applications: Used in industries for quality control and research.

TGA provides crucial data on a material’s thermal behavior and composition under varying temperatures.

The temperature limit for TGA (Thermogravimetric Analysis) typically ranges from room temperature (around 25°C) up to about 1500°C, depending on the specific capabilities of the instrument and the nature of the samples being analysed.

The range of thermal scanning in TGA (Thermogravimetric Analysis) typically spans from ambient temperature (around 25°C) up to the maximum temperature limit of the instrument, which can be as high as 1500°C or more in some advanced models. This range allows TGA to analyze materials over a wide temperature spectrum, capturing changes in mass as a function of temperature under controlled heating conditions.

No, thermal stability and boiling point are not the same.

• Boiling Point: This is the temperature at which a substance changes from liquid to vapour phase at a given pressure. It is a specific characteristic of the substance and can be determined experimentally.
• Thermal Stability: This refers to the ability of a substance to resist decomposition or degradation when subjected to heat. It indicates the temperature range over which a substance can maintain its chemical structure and properties without significant decomposition.
