TGA Thermogravimetric Analyzer
Thermogravimetric analyzer (TGA) is a type of thermal analysis technique used to study materials.Thermal stability and compositional changesThe important thermal analysis technique, its principle is toControlled atmosphere and temperature conditionsBelow, the sample is subjected to programmed heating or isothermal heating, while simultaneously measuring the change in sample weight with respect to temperature or time.
When the sample occurs during the heating processevaporation, thermal decomposition, redox reaction, dehydration or pyrolysisWhen the phenomenon occurs, the sample weight will change. By using a precise microbalance to record the weight change in real time, it is possible to obtainThermogravimetric curve (TG curve)and further analyze the mass change behavior of materials at different temperature stages. By relating these weight changes to temperature, the properties of the materials can be determined.pyrolysis temperature, composition ratio, volatile matter content, residue, and thermal stabilityOther important material properties, in addition, TGA can also be measured in different atmospheres (such as nitrogen, air, or oxygen) to study the thermal reaction behavior of materials under different environmental conditions.

Netzsch TG 209 F3 Tarsus
NETZSCHTG 209 F3 Tarsusfor high precisionThermogravimetric Analyzer (TGA)can measure materials under heating or specific atmospheric conditionsweight changesused to study the thermal stability, decomposition behavior, and composition ratios of materials.
The instrument uses a high-sensitivity microbalance and a precise temperature control system to record in real-time the changes in sample weight with temperature or time under programmed heating or isothermal conditions. When the sample due toevaporation, dehydration, thermal decomposition, oxidation or decomposition reactionsWhen weight changes occur, the material characteristics can be analyzed through the thermogravimetric curve (TG curve).
NETZSCH TG 209 F3 has good temperature control and measurement stability, and can be analyzed under different atmospheric conditions (such as nitrogen, air, or oxygen), widely used inpolymers, nanomaterials, inorganic materials, and compositesResearch on thermal characteristics.
