Comprehensive study by differential scanning calorimetry and thermogravimetric analysis with the ability to mass-spectrometric detection of emitted gases
Simultaneous Thermal Analysis generally refers to the simultaneous application of Thermogravimetry and Differential Scanning Calorimetry to one and the same sample in one instrument. The STA 449 F1 allows determination of caloric effects (transformation temperatures and enthalpies) and mass changes at the same time with outstanding reliability, resolution and accuracy.
The aim of coupling is to have all relevant gases and vapors transported from the sample area into the ion source of the mass spectrometer QMS 403С Aëolos for precise qualitative and quantitative analysis.
