THERMOGRAVIMETRIC ANALYSIS
Background
Thermogravimetric analysis involves heating a sample in an inert or oxidising atmosphere and measuring the weight. The weight change over specific temperature ranges provides indications of the composition of the sample and thermal stability. Applications include:
- Asesssment of moisture and volatiles
- Asesssment of composition
- Thermal stability
- Oxidative stability
- Decomposition kinetics
Equipment
Perkin Elmer TGA7 Thermogravimetric Analyser
- Furnace 20 to 1000°C
- Scan rates from 0.1 to 200°C/min
- Atmosphere nitrogen or air
- Pyris software
