Purpose of equipment:

• Simultaneous thermal analysis (STA) is a method of thermal analysis that makes it possible to investigate a variety of samples by two or three thermal-analytical methods. Usually those are thermogravimetry (TG), differential thermal analysis (DTA) and differential scanning calorimetry (DSC). Simultaneously, the investigation can be done on processes based on energy difference (absorbing and relaxing heat under reaction) and investigation of mass change (oxidation, degradation, etc.). STA measurement is a complex measurement that is recommended for determining the physical – chemical properties of materials, especially new ones. Simultaneously, the modelling of technological processes can be done. STA analysis makes it possible to determine characteristic temperatures (melting point, boiling point, allotropic modifications, etc.), thermal effect (melting / solidification enthalpy, combustion heat, etc.), specific heat Cp, loss or increment of mass, etc.
