TGA/STA
TGA/STA
Simultaneous Thermal Analysis (Thermo Gravimetric Analysis)
Introduction:
Thermal studies are used to study the thermal properties of the materials as a function of temperature, while the materials are subjected to a controlled temperature and atmospheric condition. TGA studies include:
- Thermogravimetry analyses (TGA) – change in weight
- Differential Thermal Analysis (DTA) – temperature difference
This technique is widely used for polymers, organics, inorganics, metals, alloys, glass, and ceramics materials.
Feature:
- High performance balance and furnace for accuracy and precision
- Top loading balance for easy sample load and unload
- Fast cooling for reduced cycle times and improving productivity
- Integrated mass flow controller extends applications flexibility

Capabilities:
- Measures weight changes in a material as function of temperature or time under controlled atmosphere
- Decomposition kinetics and composition analysis
- Thermal stability of materials
- Detect physical changes by DTA like crystallization, melting, and phase transitions
Key Applications:
- Physics, chemistry, material science, metallurgy, biology, nanotechnology
- Thermal Stability: Degradation and decomposition temperatures of polymers, composites, and natural fibers
