Thermogravimetric analysis (TG, TGA) is a method that observes the change in sample mass with temperature or time during heating, isothermal, or cooling processes, with the purpose of studying the thermal stability and composition of materials. It is widely used in the research and development, process optimization, and quality control of various fields, including plastics, rubbers, coatings, pharmaceuticals, catalysts, inorganic materials, metal materials, and composites.
The primary features of thermal gravimetric analysis are its strong quantitative nature and its ability to accurately measure the changes in mass and their rates. Based on this characteristic, it can be said that any substance experiencing a change in mass upon heating can be studied using thermal gravimetric analysis. Thermal gravimetric analysis can be used to detect both physical and chemical changes processes. We can observe that these physical and chemical changes involve mass variations, such as sublimation, vaporization, adsorption, desorption, absorption, and gas-solid reactions.
Product Features
1. The furnace heating is done with double row winding of precious metal nickel-chromium alloy wire, reducing interference and offering greater resistance to high temperatures.
2. Tray sensor, precision-engineered with noble metal nickel-chromium alloy, boasts high-temperature resistance, anti-oxidation, and corrosion resistance.
3. Power supply, separate the cooling part and the main unit to reduce the impact of heat and vibration on the micro-thermal balance.
4. Features an easy-to-use hinged lid structure. Moving the furnace body to place samples is difficult and prone to damaging the sample rod.
5. The main unit employs a water-based constant-temperature device to isolate the heat influence from the heating furnace on the housing and the micro-thermometer balance.
6. Utilizes a 32-bit ARM Cortex-M3 processor core for faster sampling and processing speeds.
7. 24-bit, 4-channel ADC samples DSC signals, TG signals, and temperature T signals.
8. The furnace body can be replaced according to customer requirements.
9. The furnace chamber features both automatic and manual lifting capabilities.
10. Compatible with infrared spectrometers

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 through a tube maintained at a high temperature (usually 200-230℃) into a heated constant-temperature gas pool within an infrared sample chamber (typically 200-230℃). The infrared spectrometer is then used to detect and analyze the structural composition of the escaping gases. As this technology addresses the limitation of thermal gravimetry, which can only provide thermal decomposition temperatures and percentage of weight loss without accurately determining the composition of volatile gases, it has been widely applied in the study of thermal stability and decomposition mechanisms of various organic and inorganic materials.
