Product Overview
The Huicheng TGA-601S Thermogravimetric Analyzer employs thermogravimetric analysis (TG/TGA) to measure changes in sample mass as a function of temperature or time under programmed temperature control. It is used to study the thermal stability and composition of materials. This instrument is widely applied in research and development, process optimization, and quality monitoring across fields such as plastics, rubber, coatings, catalysts, inorganic materials, metallic materials, and composites.

Working Principle
This instrument is based on the principle of thermogravimetric analysis. Under programmed temperature conditions (heating, constant temperature, or cooling), it measures and records the mass changes of the sample in real-time using a built-in high-sensitivity balance. This enables the analysis of material properties such as thermal stability, decomposition processes, adsorption-desorption, oxidation-reduction, and component content.
Application Fields
Plastics, rubber, coatings, catalysts, inorganic materials, metal materials, composite materials
Operating Procedure
1. Power on and preheat to ensure a constant temperature in the balance room.
2. Set experimental parameters via the touch screen, including temperature program, atmosphere, sampling frequency, etc.
3. Place the sample on the weighing pan.
4. Start the experiment; the instrument automatically controls the temperature and records mass change data.
5. After the experiment, data is automatically saved and can be analyzed.
Precautions
• Ensure the gas path of the instrument is correctly connected and well-sealed before the experiment.
• Set the temperature program and atmosphere conditions appropriately based on the sample properties.
• When placing the sample, ensure its mass is within the weighing pan's range.
• The furnace body is at high temperature; exercise caution during and after the experiment to avoid burns.
• Perform regular maintenance and calibration of the instrument to ensure testing accuracy.
