TGA Thermogravimetric Analyzer - ToronTGA
Thermogravimetric analysis (TG, TGA) measures changes in a sample’s mass as it is heated, held at a constant temperature, or cooled. This technique helps determine a material’s thermal stability and composition.
It is widely used in R&D, process optimization, and quality control across various industries, including plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic substances, metals, and composites.
Applications
TGA Thermogravimetric Analyzer - ToronTGA Measure and Study The Following Properties Of The Material
| Thermal Stability | Decomposition Process |

Performance Advantages
The redesigned furnace structure features a top-opening cover, making sample placement and testing more convenient. Heating is achieved through a dual-row coil of precious metal alloy wire, offering excellent heat resistance and reduced signal interference.
The tray sensor is crafted from a precious metal alloy disc, providing strong resistance to high temperatures, oxidation, and corrosion. The TGA Thermogravimetric Analyzer - ToronTGA includes an automatic dual-gas flow switch for faster transitions and reduced stabilization time, along with an additional input for protective gas.
Temperature control is managed through a multi-stage PID algorithm, allowing for both staged heating and consistent temperature holding. The Thermogravimetric Analyzer - ToronTGA supports dual-mode operation via the instrument interface or connected computer for enhanced experimental efficiency.
The included software enables precise tracking of material changes during thermal analysis, with spectrum collection for data interpretation. A 7-inch color touchscreen offers an intuitive interface with clear, comprehensive display of operational data.
To minimize thermal and vibration impact on the microbalance, the power supply, heat dissipation unit, and main system are designed as separate modules.

Frequently Asked Questions (FAQ)
2. What does a TGA instrument measure?
A TGA system continuously measures the weight of a sample as temperature or time progresses in a controlled environment. It detects mass loss or gain from events such as evaporation, combustion, thermal degradation, or oxidation.
3. What is the principle of TGA?
TGA operates on the principle that a substance’s mass will change when exposed to varying thermal conditions. These mass changes—caused by decomposition, desorption, or chemical reactions—are recorded with high precision as a function of temperature or time under a defined atmosphere (e.g., nitrogen, air, argon).
4. What are the main types of TGA?
There are three primary methods of thermogravimetric analysis:
-
Dynamic TGA – the sample is heated continuously at a defined rate.
-
Isothermal TGA – temperature is held constant while mass change is monitored over time.
-
Quasistatic TGA – heating is paused at intervals to allow reactions to complete before proceeding.
5. How is TGA different from DSC?
TGA focuses on mass change with temperature, making it ideal for analyzing decomposition, moisture content, and residue. DSC, on the other hand, measures heat flow during thermal transitions, such as melting or curing. Both are complementary techniques often used together to gain a deeper understanding of a material’s thermal behavior.
6. What industries typically use TGA analysis?
TGA is widely used in sectors such as:
-
Polymers and plastics – for thermal stability and filler analysis
-
Pharmaceuticals – for purity testing and drug formulation
-
Coatings and adhesives – to evaluate thermal degradation
-
Composites and ceramics – for ash content and oxidation resistance
