Simultaneous Thermal Analysis
Simultaneous Thermogravimetry and Differential Scanning Calorimetry by NETZSCH
Simultaneous Thermal Analysis (STA) generally refers to the simultaneous application of Thermogravimetry (TGA for measuring mass changes) and Differential Scanning Calorimetry (DSC for measuring energy conversion) to one and the same sample with a single instrument.
The modular design of NETZSCH simultaneous thermal analyzers allows for easy exchange of furnaces and sensors to accommodate multiple applications over a wide temperature range from -150°C to 2400°C. The top-loading design provides ideal performance and ease of use, making it the obvious choice for a flexible analytical system and evolved gas analysis such as MS, FT-IR, or GC-MS systems. A wide range of accessories, including humidity and water vapor generators, expand the application possibilities.

This concept enables safe experimentation in a 100% H2 environment or with lower concentrations of H2 mixed with non-flammable gases such as nitrogen (N2) or argon (Ar) atmospheres. It is TÜV-certified.
Accessories for DSC/TGA and STA
Get an overview of all crucibles and sensors for DTA, DSC, TGA and STA measurements.
You will find many different crucible materials listed, and a variety of types and special shapes. From among these options, we can assist you in selecting the appropriate crucible size and material for your specific application, whether standard or special. In addition to standard aluminum crucibles, our portfolio includes autoclaves with low to medium or high-pressure tightness, as well as ones for determining the Oxidative-Induction Time (Oxidative-Induction Time (OIT) and Oxidative-Onset Temperature (OOT)Oxidative Induction Time (isothermal OIT) is a relative measure of the resistance of a (stabilized) material to oxidative decomposition. Oxidative-Induction Temperature (dynamic OIT) or Oxidative-Onset Temperature (OOT) is a relative measure of the resistance of a (stabilized) material to oxidative decomposition.OIT) and solid fat index (SFI). We offer crucibles made of ceramics or metals covering a wide temperature range.
Detect and Identify Evolved Gases with NETZSCH STA Instruments
By coupling gas analysis techniques such as FT-IR (Fourier Transform Infrared), MS (Mass Spectrometry) or GC-MS (Gas Chromatography – Mass Spectrometry) to an STA 509 Jupiter®, information about the nature of the evolved gases as a function of time or temperature can be obtained.
About the STA Method
Simultaneous Application of DSC and TGA
The simultaneous application of Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) to a single sample in an STA instrument yields more information than separate application with two different instruments. Simultaneous TGA-DTA/DSC measures both the heat flow (DSC) and mass change (TGA) of a sample as a function of temperature or time under a controlled atmosphere.
- The test conditions are perfectly identical for the TGA 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.).
- 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.)

Why Should You Choose a NETZSCH STA 509 Instrument for Your Thermal Analysis Needs?
Today, the STA is one of the most flexible analytical instruments in the NETZSCH portfolio. Users can select from among various types of furnaces, sensors, sample carriers, thermocouples, crucibles and other accessories. By using special furnaces, also measurements under humid atmospheres can be carried out under certain corrosive conditions or even at the highest temperature range.
- Wide Temperature Range
The NETZSCH STA 509 Jupiter® covers an extremely wide temperature range from -150°C to 2400°C, thanks to the possibility choosing from among 12 different user-exchangeable furnace types. Furthermore, the Select and Supreme versions can be both equipped with a second furnace.
- Special Setups for Special Atmospheres
Our STA supports mid-test atmosphere changes, making it ideal for studying hydrogen- or moisture-sensitive materials. Optional features, such as the coupling possibility to evolved gas analyzers (FT-IR, MS and GC-MS), humidity generators and the advanced H₂Secure system, further enhance its capabilities. For highly sensitive applications, a glove box version is available.
- Modular System with Quick Sensor Exchange
The NETZSCH STA 509 system is a highly modular platform, that can be tailored to nearly all customer needs in terms of temperature range, atmospheres and sensor technology. Thanks to its top-loading design, it features a "Quick-Connect" system that allows sample carriers (TGA-DSC, TGA-DTA and pure TGA) to be changed in seconds. In addition, each sensor is automatically recognized by the Proteus® software and stored in a sample carrier database.
