The TGA 4000 thermogravimetric analyzer consists of a microbalance coupled to an oven, which enables the variation in a sample’s mass during heating-induced transformations to be monitored.
- Temperature range: 30°C to 1000°C
- Powder weight required: from 5 mg to 200 mg
- Under controlled atmosphere (nitrogen) or ambient air.
Principle of analysis :
The sample is placed on the weighing module in an alumina pod, under an inert atmosphere (nitrogen), then heated according to a programmed temperature profile (single gradient, multiple steps, etc.).
Several characteristics can thus be determined: oxidation kinetics, degradation or phase change temperatures, moisture absorption or desorption, quantity of organic/inorganic compounds, decomposition point, etc.
Analyses carried out on the instrument :
Monitoring of mineralogical transformations
Quantification of mineral phases
Quantification of organic phases
