Thermogravimetric analysis (TG, TGA) involves observing the change in sample mass with temperature or time during heating, isothermal, or cooling processes, with the aim of studying the thermal stability and composition of materials. It is widely used in research and development, process optimization, and quality control across various fields, including plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metals, and composites.
The primary characteristics of thermal gravimetric analysis are its strong quantitative nature and the ability to accurately measure changes in the mass and their rates. Based on this feature, it can be said that any substance that undergoes mass changes upon heating can be studied using thermal gravimetric analysis. Thermal gravimetric analysis can be used to detect physical and chemical changes processes. We can observe that these physical and chemical changes are accompanied by mass changes, such as sublimation, vaporization, adsorption, desorption, absorption, and gas-solid reactions.

Thermal Gravimetric Analyzer - Infrared Coupling Introduction
Thermal Gravimetric Analyzer-Infrared Spectrometer Coupling System (hereinafter referred to as TGA-IR Coupling) utilizes purge gas (usually nitrogen or air) to introduce volatiles or decomposition products generated during the thermal gravimetric process through a connecting tube maintained at a constant high temperature (typically 200-230°C) into a heated, isothermal gas cell within an infrared sample chamber (usually 200-230°C). The infrared spectrometer is then used to detect and analyze the structural composition of the escaping gas components. Due to its ability to address the limitations of thermal gravimetry, which only provides thermal decomposition temperatures and weight loss percentages without precise identification of volatile gas components, this technology is widely applied in the study of thermal stability and decomposition mechanisms of various organic and inorganic materials.
