How to Detect and Identify Evolved Gases

Almost Half a Century of Development Experience in Coupling Technologies

40 Years of Coupling with Mass Spectrometers

By coupling a Thermobalance (TG, TGA), Simultaneous Thermal Analyzer (STA, TGA-DSC) or Dilatometer (DIL) with a Quadrupole Mass Spectrometer (QMS), it is possible to detect and identify evolved gases in exact time correlation with TGA or STA signals. NETZSCH has over 40 years of experience in gas transfer and can offer you well-proven coupling systems: the unique SKIMMER Coupling, the capillary coupling for the QMS 403 Aëolos® Quadro, and the GC-MS Coupling.

25 Years of Coupling with FT-IR Systems

Combination with an FT-IR (Fourier Transform Infrared Spectrometer) has become an absolute must, especially in the polymer-producing, chemical and pharmaceutical industries. NETZSCH Analyzing & Testing has been collaborating with the well-known producer of spectrometers, Bruker Optics GmbH, since 1993. FT-IR coupling is “more than the sum of its parts”. Let our intelligent hardware and software designs work for you!

10 Years of Coupling with GC-MS Systems Enable an Improved Gas Analysis of the Vaporized Materials

The GC (gas chromatograph) separates gas mixtures based on the differences in component distribution between a stationary phase (e.g., inner coating of a capillary) and a mobile phase (e.g., He). The purge gas rapidly carries away gas components with a low affinity for the stationary phase. Gases with a high affinity for the stationary phase will follow with a significant time delay (“retention time”). At the outlet of the GC column, the MS is connected. Using the pre-separation of the gases by the GC as a basis, the MS provides detailed structural information about the compounds released.

Quantification of the Evolved Gases and More

PulseTA® is a perfect tool for achieving quantitative gas detection in separate calibration runs or even online during a sample measurement. In addition, PulseTA® also allows for studying gas/solid reactions with stepwise control of the process via the injection of a reactive gas, and simplifies adsorption/desorption experiments and studies of catalytic reactions.
