FT-IR Coupling

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 couplingcan 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
