TG-DSC

TECHNICAL SHEET

General description

Thermogravimetry (TG) is a method of thermal analysis that continuously measures the mass of a sample over time as the temperature is changed. During heating, both the temperature at which the sample looses (or gains) weight as well as the exact mass loss (gain) can be determined accurately, thus providing information about thermal stability and phenomena such phase transitions, decomposition, oxidation, reduction,…

Differential scanning calorimetry (DSC) provides information about thermal transitions within a sample. By heating a sample together with  a reference standard, the difference in heat fluxes necessary to maintain the same temperature allows to access to exo- or endothermic phenomena such as melting, crystallization, glass transition,…

The TG-DSC combines both these techniques within a single measurement, with an accurate control of temperature ramping and gas flows.

Reporting

Data treatment is performed via the build-in software (Calisto from SETARAM).

A standard report will provide the most pertinent data such as % mass change, Heat flow, Temperature and time. Optional calculations can be provided on demand.

The raw data will be supplied on demand as an Excel^® file.
