Evolved Gas Analysis (EGA)

PERSEUS® TG 209 F1 Libra®


The Perfect TGA-FT-IR Coupling Solution


It is robust and stands out by virtue of its high performance, compactness and attractive price. This instrument integrates the small but powerful FT-IR with the TGA and has the potential to fit into any laboratory – be it in universities or industry, quality assurance or development.


It can be employed for the following application areas:

  • Analysis of decomposition processes

  • Evaporation, outgassing

  • Desorption behavior

  • Solid gas reactions

  • Detection of volatiles

  • Compositional analysis

  • Analysis of aging process
