Thermal analysis

Simultaneous thermal analysis (STA ) is an established method in the characterization of materials and usually refers to the simultaneous measurement of mass changes by means of thermogravimetry (TG ) and caloric effects of a sample by means of differential scanning calorimetry ( DSC) during a controlled temperature program. A STA apparatus has several fundamental advantages:

On one hand, can be determined in the simultaneous thermal analysis of both the temperature-dependent mass changes (TG ) and the caloric effects (for example, phase transition temperatures and enthalpies ) by DSC in a single measurement, which reduces the time required and often expensive and difficult to manufacture sample material saves.

On the other hand, the TG and DSC results of an STA measurement are actually comparable and correlated since exactly the same measurement conditions prevail and also influences of different sample preparations are excluded.

Finally, the exact knowledge of the current sample mass for accurate enthalpy by DSC also always given.
