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, allowing for accurate measurement of mass changes and their rates. Based on this feature, it can be said that any substance undergoing mass changes upon heating can be studied using thermal gravimetric analysis. Physical and chemical changes that can be detected by thermal gravimetric analysis include sublimation, vaporization, adsorption, desorption, absorption, and gas-solid reactions.
Product Features
The furnace heating is made with double-row winding of precious metal nickel-chromium alloy wire, reducing interference and providing better resistance to high temperatures.
2. Tray sensor, precision-engineered from noble metal nickel-chromium alloy, boasts high-temperature resistance, anti-oxidation, and corrosion resistance.

Thermal Gravimetric Analyzer - Infrared Coupling Introduction
Thermal Gravimetric Analyzer-Infrared Spectrometer Coupling System (hereinafter referred to as TGA-IR Coupling) utilizes purge gas (typically nitrogen or air) to introduce volatile components or decomposition products generated during the thermal gravimetric process into a heated, isothermal gas cell (usually at 200-230°C) within an infrared sample chamber via a connecting tube maintained at a high temperature (typically 200-230°C). The infrared spectrometer is then used to detect and analyze the structural composition of the escaping gas components. As this technology addresses the limitation of thermal gravimetry, which can only provide thermal decomposition temperatures and percentage of weight loss, but not the exact composition of volatile gases, it has been widely applied in the study of thermal stability and decomposition mechanisms of various organic and inorganic materials.
