Thermogravimetric Analysis TGA or Thermogravimetry TG

NETZSCH instruments for thermogravimetry have a compact design and are equipped with high-resolution balance systems. The top-loading sample arrangement allows for easy operation and measurement of the temperature directly at the sample.


Almost all NETZSCH thermobalances are vacuum-tight and allow for measurement of mass changes under defined atmospheres. The optional c-DTA ® signal additionally yields information on exothermal and endothermal processes in the sample, even if they are not related to a mass change.


Heated coupling adapters for gas analysis systems such as QMS, FTIR , or GC-MS can be added on to many thermobalances. The thermogravimetric analyzers of the 400 series can be equipped with DSC and/or DTA sample carriers at any time in order to form full-fledged TGA-DSC or TGA-DTA instruments (STA).


NETZSCH thermobalances meet respective instrument and applications standards, including ISO 11358, ISO/DIS 9924, ASTM E1131, ASTM D3850, DIN 51006.

It serves for investigating:

  • Mass changes
  • Decomposition behavior
  • Pyrolysis
  • Water content
  • Identification of solvents (even intercalated ones)
  • Interactions with the surrounding gas atmosphere, e.g., oxidation
  • Shelf life
  • Thermal kinetics (in combination with Kinetics Neo)
  • Identification of evolved gases (coupled to a gas analyzing system such as FT-IR, MS or GC-MS)


Features of the TG 209 F1 Nevio:
Innovative software solutions – AutoEvaluation and Identify

The unique AutoEvaluation software feature offers operator-free evaluation of thermogravimetric effects. Identify is a database-driven recognition system for the identification and classification of materials – all it takes is one click.

Direct detection of the sample temperature ‒ determination of endo- and exothermal effects

The sample thermocouple is in direct contact with the sample crucible and records all temperature changes inside the sample. Based on this, a c-DTA® signal can be calculated; this displays caloric effects and can be used for temperature calibration.

1100°C at the sample – the temperature displayed corresponds to the sample temperature

The sample-temperature-control mode allows for achieving the specified maximum temperature for the TG 209 F1 Nevio system of 1100°C at the sample.

Fast, corrosion-resistant ceramic micro furnace

The furnace is able to withstand even halogenated evaporation products. In addition, the low volume of the furnace in combination with the water-cooling provides a much faster cooling speed than air-cooled systems.

Robust top-loading balance arrangement

Easy accessibility to the sample and crucible as well as the ability to disconnect the sample carrier from the balance during loading or unloading of the sample are only two examples of how safe handling and maximum usability are ensured.

Ideally suited for being coupled to evolved gas analyzers

The vacuum-tight design of the instrument, which allows for the software-controlled evacuation and backfilling of inert gas (via the optional AutoVac), is the feature that provides uniform test conditions and ensures reproducible results. In addition, low gas flow rates result in high detection sensitivity as the evolved gases are only slightly diluted.

High sample throughput with the automatic sample changer

The automatic sample changer (ASC) is designed for measuring up to 192 samples (2 x 96) plus 12 extra positions for calibration materials or empty crucibles. The optional piercing device allows for the piercing of aluminum lids shortly before the sample pan is inserted into the furnace.
