Evolved Gas Analysis (EGA) is the perfect tool for characterizing the thermal behavior of organics, inorganics, or polymers in more detail, elucidating the chemistry behind the processes.
The PERSEUS® TGA 209 F1 Libra® 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.
Any existing NETZSCH TG 209 F1 Libra® system can be upgraded with the PERSEUS® coupling.
The PERSEUS® TG 209 F1 Libra® can be employed for the following application areas:
- Analysis of Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition processes
- Solid-gas reactions
- Compositional analysis
- Evaporation, outgassing
- Detection of volatiles
- Analysis of aging processes
- Desorption behavior

Affordable Gas Analysis
The unrivaled instrument alliance serves as an innovative coupling technique, even for a narrow budget. It has what it takes to become an integral part of any laboratory and may well become indispensable for future needs.
No Liquid Nitrogen required
The DLaTGS (deuterated L-alanine doped triglycine sulfate) detector operates without the need for liquid nitrogen. This system is thus particularly well-suited for test runs with an autosampler (ASC) or long-term measurements.
