MCL's thermal analysis suite of characterization capabilities includes three techniques: Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC) and Evolved Gas Analysis (EGA) via a TGA coupled to a Mass Spectrometer. The data obtained by these techniques and applications examples are shown in the table below.  

Technique Data Obtained Applications
TGA Weight loss/gain in mg and %
Temperature of weight change transition
Thermal and Oxidative Stability of Materials • Composition of Multi-component Systems •The Effect of Reactive or Corrosive Atmospheres on Materials •Moisture and Volatiles Content of Materials
DSC Heat flow changes with temperature Melting and Crystallization temperatures • Glass transition temperature (amorphous materials) • “cold” crystallization • Heat capacity • Cure kinetics • Crystalline content
EGA EGA Composition of gasses (m/z) evolved as temperature increases Identification of individual degradation products, residual solvents and contamination • By-product analysis • Reaction elucidation, stoichiometry
