Thermogravimetric Analysis (TGA)

Thermogravimetric Analysis (TGA)

Mettler Toledo TGA 2

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 TGA 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
