Thermogravimetric Analysis / Thermogravimetry - TGA

TG 209 F3 Tarsus - Thermo-Microbalance (TGA-Thermogravimetric Analyzer)

Together with the DSC 200 F3 Maia®, the new thermo-microbalance, TG 209 F3 Tarsus, represents a cost-effective overall concept, tailored not only to the quality assurance of polymers, but also to routine applications in the fields of organic chemistry, pharmaceuticals, cosmetics and food.

This new basic instrument for thermogravimetric measurements offers already a resolution of 0.1 µg. The TG 209 F3 Tarsus operates between room temperature and 1000°C with freely selectable heating rates from 0.001 K/min up to 100 K/min. The accurate sample temperature is detected by a thermocouple in direct contact with the sample crucible. Through the reliable vertical construction with sample carrier lift, the thermo-balance as a top-loader, is easy and safe to use, with no hang-down wires or exposed fragile parts.

• NEW: The fifth generation of the Proteus® measurement and analysis

software has been released.


The calculated DTA-signal c-DTA® (option) not only is ideal for temperature calibration. During sample measurements it yields important information regarding endothermal processes (e.g. vaporization with mass loss or melting without mass loss) as well as exothermal reactions.

For the TG 209 F3 Tarsus we offer an automatic sample changer (ASC) for up to 20 samples also in different crucible types.

TG 209 F1 Iris - Thermo-Microbalance (TGA-Thermogravimetric Analyzer)
The TG 209 F1 Iris® offers a platform identical to that of the DSC 204 F1 Phoenix®, together comprising an instrument generation that stands out due to unique design and revolutionary flexibility.


The thermo-microbalance operates in a temperature range between 10°C (thermostat cooling) and 1000°C with freely selectable heating rates from 0.001 K/min up to 100 K/min. The exact sample temperature is detected by a thermocouple in direct contact with the crucible.


The vacuum-tight, upright assembly and the integrated mass flow controllers for the purge and protection gases create ideal conditions for coupling to an FTIR or MS for gas analysis - even with an installed automatic sample changer (ASC) for up to 64 sample crucibles.


Important hardware extensions like the automatic evacuating and gas-filling system AutoVac, as well as software features such as c-DTA® for the calculated DTA-signal, make the
TG 209 F1 Iris® to the most versatile TGA-system for highest demands in research and development as well as in quality assurance.

TG 449 F3 Jupiter - Thermo-Microbalance (TGA- Thermogravimetric Analyzer)
The TG 449 F3 Jupiter® is the workhorse for thermogravimetric analyses of a moderate to high sample weights from -150°C into the high temperature range of 2000°C.

The vertical design with top-loaded samples ensures total protection of the balance, which is on the bottom, through accurate flow of the purge and protective gases in a natural vertical path to the top, with optimal conditions for coupling FTIR and MS gas analysis systems to the heated furnace outlet.
The TG sample carriers are always equipped with a thermocouple for direct measurement of the temperature at the sample.

The high capacity of the balance along with constant resolution over the entire weighing range provide the best conditions for using the wide variety of ceramic or metallic sample crucibles and pans in different shapes and sizes.

Of course, vacuum-tight construction providing for pure atmospheres goes without saying.

The TG 449 F3 Jupiter® is designed for upgrading to simultaneous TG-DSC or simultaneous TGA-DTA. The TGA sample carriers can be exchanged with TGA-DSC or TGA-DTA sample carriers in a matter of seconds so that a very cost-effective upgrade can be made at any time into a full-fledged, universal STA.

The TG 449 F3 Jupiter® is one of the versatile TGA systems for routine use in material research and development as well as in quality assurance – primarily in the area of inorganics.

TG 449 F1 Jupiter - Thermo-Nanobalance (TGA-Thermogravimetric Analyzer)
The TG 449 F1 Jupiter® is number one among thermo-nanobalances because of the concept of a vacuum-tight instrument design and the successful combination of the highest resolution and unsurpassed long-term stability.

Flexibility for all applications involving organic and inorganic samples is achieved with six exchangeable furnaces for the broad temperature range of -150°C to 2000°C and with a multitude of sample carriers and crucibles.

The vertical design and top-loaded samples ensure total protection of the digital ultra-nanobalance, which is on the bottom, through accurate flow of the purge and protective gases in a natural vertical path to the top. This also provides optimal conditions for coupling FTIR and MS gas analysis systems to the heated furnace outlet. The mass flow controllers for 3 gases are already integrated into the base instrument.

The TGA sample carriers are always equipped with a thermocouple for direct measurement of the temperature at the sample crucible. There are a number of different thermocouple types to choose from, depending on the application.
Unique is the isolation of the sample carrier from the balance upon automatic opening of the furnace to load a sample. This guarantees reliable mechanical protection of the high-resolution ultra-microbalance and thus a long service life.

From the outset, the TG 449 F1 Jupiter® was designed for upgrading for simultaneous TGA-DSC or simultaneous TGA-DTA. The TGA sample carriers are user-exchangeable within a matter of seconds, so a very cost-effective upgrade can be made at any time to an STA with superlative TGA and DSC and DSC-C_p or DTA performance.

The TG 449 F1 Jupiter® is the most powerful and versatile TGA system for research and development as well as all material characterization problems for the area of organic and inorganic materials.

The TG 409 CD is based on the classic concept of a thermobalance in a vertically-arranged instrument with top-loaded samples. This design ensures total protection of the digital balance, which is on the bottom, through accurate flow of the purge and protective gases in a natural vertical path to the top, with optimal conditions for coupling FTIR and MS gas analysis systems to the heated furnace outlet. The variety of materials available for components and seals that come into contact with the gases means that measurements are also possible in corrosive gas atmospheres.


Single and double hoist systems for the different types of exchangeable furnaces open up the extremely broad temperature range of -160°C to 2000°C, supported by a multitude of sample carriers and crucibles.


The TGA sample carriers are always equipped with a thermocouple for direct measurement of the temperature at the sample crucible. There are a number of different thermocouple types to choose from, depending on the application.

When equipped with the Skimmer mass spectrometer coupling, the TG 409 CD becomes the most sophisticated instrument on the market for the analysis of condensable vapors that evolve from a sample at temperatures ranging up to 1450°C or 2000°C.

The robust TG 429 CD can be equipped with side-mounted motorized hoists for the maximum-temperature 2400°C tungsten furnace or for the Skimmer mass spectrometer coupling. In addition, top-mounted single and double hoisting devices for the different types of exchangeable furnaces provide for an extremely broad temperature range of -160°C to 1700°C.


As with all NETZSCH thermobalances, the TGA sample carriers are equipped with a thermocouple for direct temperature measurement at the sample crucible. Depending on the application, a selection of different thermocouple types is available. The TG 429 CD is also designed for upgrading to simultaneous TGA-DSC or simultaneous TGA-DTA. The TGA sample carriers can be exchanged with TGA-DSC or TGA-DTA sample carriers in a matter of seconds so that an upgrade can be made at any time into a powerful and versatile STA.



The maximum-temperature TGA and TGA-DTA sample carriers are made of tungsten in the hot zone and have exchangeable tungsten-rhenium thermocouples. Because measurements are carried out in pure gas atmospheres or under high vacuum, these proven sample carrier systems have a long service life.
