TGA4000 (Perkin Elmer)

Figure 49

Device:

The thermogravimetric analyzer TGA 4000 consist of a micro-balance coupled to an oven, which allows to follow the variation of a sample weight during eating-induced transformations.

  • Temperatures range: 30°C – 1000°C
  • Sample weight: 5 mg to 200 mg
  • Under controlled (nitrogen) or ambient atmosphere.

Principle:

The sample is placed on the weighting module in an alumina holder, then heated following a programmed temperature profile (simple gradient, multiple plateau, etc..)

The measured weight loss allows to determine several sample characteristics: oxidation kinetics, degradation/phase transformation temperatures, humidity absorption or desorption, inorganic/organic amounts, decomposition points, etc..

Routine measurements:

  • Follow of mineralogical transformations

  • Quantification of mineralogical phases

  • Quantificatin of organic phases
