Hot Spots in Evolved Gas Analysis: The New TGA-FT-IR Coupling

The pairing of thermal analyzers with Fourier transform infrared spectrometers (FT-IR) has become a cornerstone in the world of materials analysis, especially in the polymer-producing, chemical and pharmaceutical industries. Learn more about the new coupling system with an extended temperature range, based on a pairing of the two instruments NETZSCH TG 209 F1 Libra®® and Bruker INVENIO FT-IR. 

The pairing of thermal analyzers with Fourier transform infrared spectrometers (FT-IR) has become a cornerstone in the world of materials analysis, especially in the polymer-producing, chemical and pharmaceutical industries. The well-established technique of coupling thermogravimetry (TGA) with infrared spectrometers (FT-IR), for instance, allows for the simultaneous investigation of Thermally induced reactionA thermally induced reaction is a decomposition reaction exclusively started through heat treatment. thermally induced mass losses and the associated gas products that evolve. This allows for deeper insights into the origin of observed material behavior and ultimately leads to a better understanding of material properties and potential applications.

For the technical realization of this complex analytical method, NETZSCH has been collaborating with Bruker Optics, one of the leading manufacturers of infrared spectrometers, since 1993.

As the latest result of this collaboration, NETZSCH and Bruker are now able to offer their customers a new coupling system with an extended temperature range, based on a pairing of the two instruments NETZSCH TG 209 F1 Libra®®® and Bruker INVENIO FT-IR

The system is rooted in a new development involving the coupling interface, consisting of furnace adapter, transfer line and IR gas cell. It enables continuous heating of the gas circuit up to 370°C – much higher than the previously typical range of up to 200°C. As a result, the new system allows for such advancements as improved detection of high-boiling components in the sample gas, thus expanding the application range of TGA-FT-IR coupling.
