Thermogravimetric Analysis (TGA)
Technique:
Thermogravimetric analysis (TGA) measures the mass of a sample while the sample is heated or cooled in a defined atmosphere. The main use of thermogravimetric analysis is to characterize materials with regard to their composition.
Instrument:
Mettler Toledo TGA 2
System Capabilities:
- Temperature range: room temperature to 1100 °C
- Atmosphere: nitrogen, air, or oxygen gas
- Heating rate: 0.02 to 250 °C/min
- Sample mass range: ≤1 g (typically 10–15 mg used)
Selected Applications in Industry:
- Characterization of the thermal properties of materials such as plastics, elastomers and thermosets, mineral compounds, and ceramics, as well as for chemical products
- Measurement of composition (e.g., organics, carbon black, filler), purity, decomposition reactions, decomposition temperatures, and absorbed moisture content
