Coupling to a Fourier Transform Infrared Spectrometer

More than just the sum of its parts

Especially in the polymer field as well as in the pharmaceutical and chemical industries, it can be very useful to have knowledge about the gases that evolve during a process, curing/cross-linking, decomposition or any other reaction.
With the vacuum-tight thermal balances and simultaneous thermal analysis instruments TG 209 F1 Libra®, TG/STA 449 F3 Jupiter® and TG/STA 449 F1 Jupiter®, TG/STA 449 F5 Jupiter®, STA 2500 Regulus, DIL 402 Expedis Select & Supreme, and TMA 402 F1/F3 Hyperion®, as well as with the dynamic differential calorimeters DSC 404 F1 Pegasus® and DSC 204 F1 Phoenix®, NETZSCH offers you efficient systems for coupling to a Fourier Transform Infrared Spectrometer (FT-IR). The transfer line and the connection adaptors to the furnaces can be heated up to 230°C to prevent condensation of the decomposition products to the greatest extent possible. For spectra interpretation, extensive gas phase libraries are available.

The FT-IR coupling can be employed for the following application areas:

  • Decomposition
  • Dehydration
  • Residual solvent content
  • Pyrolysis
  • Solid-gas reactions
  • Combustion
  • Oxidation
  • Corrosion
  • Catalysis
  • Compositional analysis
  • Binder burn-out
  • Coal analysis
  • Polymer content
  • Ash content
  • Evaporation, outgassing
  • Analysis of decomposition processes
  • Detection of volatiles
  • Analysis of aging processes
  • Desorption behavior


With the PulseTA® technique an exactly defined quantity of gas is injected to the purge gas of the thermobalance (TGA) or the simultaneous thermal analysis instrument (STA).



The FT-IR coupling runs under OPUS and  Proteus® software on Windows®. Proteus® includes everything you need to carry out a measurement and evaluate the resulting data. Easy-to-understand menus and automated routines make Proteus® extremely user-friendly while still allowing for sophisticated analysis. Proteus® software is licensed with the instrument and can of course be installed on other computer systems.


  • Simultaneous measuring, data acquisition, and data storage with the two software packages: Proteus® (NETZSCH) for thermal analysis data, and OPUS (Bruker Optics) for FT-IR spectra and traces
  • OPUS/CHROM software as 2D and 3D plots for FT-IR and TG/STA/DSC measuring curves as functions of time and temperature
  • OPUS/SEARCH with spectra library
  • Traces for evaluation of characteristic temperatures and peak area together with thermal analysis curves
  • Gram-Schmidt plot with temperature and peak area calculation together with thermal analysis curves

QMS 403 Aëolos Quadro - Quadrupole Mass Spectrometer Coupling

The QMS 403 Aëolos Quadro is a very compact mass spectrometer with a heated capillary inlet system, specially designed for routine analysis of volatile decomposition products of thermal analysis (instrument for EGA: evolved gas analysis).

TGA/STA-GC-MS Coupling

NETZSCH, in collaboration with JAS (Joint Analytical Systems), has forged a breakthrough improvement in evolved gas analysis (EGA). What sets the new coupling system apart is the fact that the start of the measurement is event-driven. This enables temperature-correlated detection of the substances released, which in turn allows for direct correlation with mass loss steps.
