Thermogravimetric Analysis
Thermogravimetric Analyzer Technology by NETZSCH
Thermogravimetric analysis or thermogravimetry (TGA/TG) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about the Thermal StabilityA material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer). thermal stability of samples, their composition (via the Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition of different components), Solid-Gas ReactionsSolid-gas reactions are a type of heterogeneous solid-state reaction occurring when a reactive solid is exposed to a stream of reactive gas. Typical examples of solid-gas reactions are sorption and corrosion of metals.solid-gas reactions such as absorption, desorption, OxidationOxidation can describe different processes in the context of thermal analysis.oxidation or reduction and, using the c-DTA® functionality, even Phase TransitionsThe term phase transition (or phase change) is most commonly used to describe transitions between the solid, liquid and gaseous states.phase transitions.
Thermogravimetry is a widely used analytical method in the chemical and pharmaceutical industries. It is used to characterize polymers, food, cosmetics, drugs, and many other materials.

Detect and Identify Evolved Gases with NETZSCH Thermobalances
By coupling gas analysis techniques such as FT-IR (Fourier Transform Infrared), MS (Mass Spectrometry) or GC-MS (Gas Chromatography – Mass Spectrometry) to a TG 309 Libra®, information about the nature of the evolved gases as a function of time or temperature can be obtained.
About the TGA Method
The Measuring Principle of TGA
Thermogravimetric analysis (TGA) is a precise analytical technique used to track changes in the mass of a sample over time and/or temperature under a defined and controlled environment with respect to heating rate, gas atmosphere, flow rate, crucible type, etc. It can accurately detect weight changes down to fractions of a microgram. This high sensitivity allows for the determination of even the smallest changes in the physical and chemical properties of a material.
NETZSCH thermobalances meet respective instrument and application standards, including ISO 11358, ISO/DIS 9924, ASTM E1131, ASTM D3850, DIN 51006.

Eco Mode – Uses Energy Only When Needed
FOCUS ON EFFICENCY AND A MORE SUSTAINABLE LABORATORY
The NETZSCH TG 309 Libra® series offers a programmable energy-saving Eco Mode, which allows the chiller to be switched off automatically. The software provides a user-defined schedule to activate either Idle or Eco Mode. This eliminates the waiting time that would occur if the instrument were completely shut down, by reactivating the gas flow and thermostat as required, so that the instrument is ready for the first measurement on schedule. Switching the unit to Eco Mode will save 1 kW of electricity, which can sum up to over 6000 kWh per year.
Why Should You Choose a NETZSCH TG 309 Thermobalance for Your Thermal Analysis Needs?
The NETZSCH TG 309 Libra® thermogravimetric analyzer sets a new standard in high-precision thermal analysis. Designed to meet the highest demands in thermogravimetric testing, this TGA system delivers exceptional sensitivity, baseline stability, and user-friendly operation.
- Top-loading ultra-sensitive weighing system
With an outstanding balance resolution of up to 10 ng and low baseline drift for precise weight change detection, the NETZSCH TG 309 Libra® series helps to get results even more precisely and quickly. This series no longer requires a separate baseline correction when using the integrated BeFlat® baseline run for typical temperature profiles.
- Advanced gas switching system
Benefit from four mass flow controllers to streamline gas switching and mixing. There is no need to change and clean gas connections, thus saving the user valuable time and minimizing clogging risks.
- Unique magnetic dampers
Eliminate environmental effects: Magnetic levitation separates the instrument from the surface on which the thermobalance stands. In this way, measurement effects do not have external influences superimposed.
- Various user-exchangeable sample carriers
Choose between a great number of crucibles and sample carriers, including corrosion-resistant and high sensitivity, for specific applications and reduced maintenance costs
- Expert support and training
Benefit from the expertise of our dedicated and continuously trained professionals across our service, laboratory, training, and sales departments. Our team with several decades of experience is committed to providing exceptional support and comprehensive training in order to ensure that you get the most out of your NETZSCH thermobalance.
