Evolved Gas Analysis (EGA)

By coupling the thermal analysis instrument with the Quadrupole Mass Spectrometer (QMS) the detection and identification of the evolved gases (evolved gas analysis - EGA) are possible in exact time correlation with the other thermal analysis signals. For gas transfer, NETZSCH can rely on more than 30 years experience and can offer you well-proven coupling systems: the unique SKIMMER Coupling, the capillary coupling for the QMS 403 C Aëolos®, and the GC-MS Coupling.

The combination with an FTIR (Fourier Transform Infrared Spectrometer) has become an absolute must, especially in the polymer producing, chemical and pharmaceutical industry. For more than 15 years NETZSCH Analyzing & Testing cooperates with the well-known producer of spectrometers Bruker Optik GmbH.
The FTIR coupling is “more than the sum of its parts”. Profit by our intelligent hardware and software concept!

With the unique PulseTA® (pulse thermal analysis) a quantitative evolved gas analyis – both with QMS and with FTIR can be reached.

QMS 403 C Aëolos® - Quadrupole Mass Spectrometer
The QMS 403 Aëolos® 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).

QMS 403/5 SKIMMER - Coupling system
Highest detection sensitivity through direct coupling of the STA 409 CD with a quadrupole mass spectrometer (QMS) - evolved gas analysis (EGA) method.

TG-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.
