Ideal Uses Ideal uses of the TG/DTA technique include:
- Thermal stability studies
- Monitoring mass changes of materials under controlled gas atmosphere and temperature: volatiles, reactive gas evaluation, filler content, compositional analysis, material identification
- Phase transitions of metals and alloys
- Qualitative analysis of phase transitions: melting, Tg, crystallization
- Determining the effect of oxidative or reductive atmospheres on materials
- Analysis of polymers, organic and inorganic materials
Technical Specifications Temperature: ambient to 1100°C
Atmosphere: Inert – Argon, Nitrogen; Oxidative – O2, Air; Reductive – Hydrogen/Argon mixture
Sample: 0.1 – 180 mg
Heating Rate: 0.01 to 100.00°C/minute
Strengths Rapid screening of thermal properties of materials
Simultaneous acquisition of thermogravimetry and phase transition data
Small sample size
Choice of atmospheres (inert or reactive)
Used for high temperature analysis of phase transitions
Limitations Does not measure heat capacity
Not quantitative for enthalpy change (e.g. heat of fusion) measurement
