Simultaneous Thermogravimetry – Differential Scanning Calorimetry
Simultaneous Thermal Analysis (STA) is based on standards, e.g., ISO 11358, ASTM E793, DIN 51004, DIN 51006, DIN 51007. It generally refers to the simultaneous application of Thermogravimetry (TGA) and Differential Scanning Calorimetry (DSC) to one and the same sample in a single instrument.
The simultaneous application of Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC) to a single sample in an STA instrument yields more information than separate application in two different instruments:
- The test conditions are perfectly identical for the TG and DSC signals (same atmosphere, flow rate, vapor pressure on the sample, heating rate, thermal contact to the sample crucible and sensor, radiation effect, etc.).
- The analyzability of the signals is improved, since two or more sets of information concerning sample behavior are always simultaneously available (differentiation between phase transformation and Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition, between addition and condensation reactions, recognition of PyrolysisPyrolysis is the thermal decomposition of organic compounds in an inert atmosphere.pyrolysis, OxidationOxidation can describe different processes in the context of thermal analysis.oxidation, and combustion reactions, etc.)
Since the early years of its existence, NETZSCH-Gerätebau GmbH has given high priority to the development and continuing optimization of its Simultaneous Thermal Analyzers; these have today taken on a market-leading position as a result of their perfect technology.
The advantages are obvious:
The test conditions are perfectly identical for the TGA and DSC signals (same atmosphere, gas flow rate, vapor pressure on the sample, heating rate, thermal contact to the sample crucible and sensor, radiation effect, etc.). Furthermore, sample throughput Is improved as more information can be gathered from each test run.
