EGA gas analysis
Couplings for thermal analysis
Couplings / Evolved Gas Analysis (EGA)
By coupling the thermal analyzer (for example a thermobalance TGA or Simultaneous Thermal Analyzer STA (TGA+DSC)) with the fast quadrupole mass spectrometer (QMS) or FTIR spectrometer (Fourier Tansform Infrared), it is possible to detect the gas separation and identify the separated components in exact temporal correlation with the other thermal analysis signals.
Our EGA devices
Typical couplings in simultaneous analysis:
- TG-DSC-MS (Thermogravimetry, Differential Scanning Calorimetry, mass spectrometer)
- TGA-MS (thermobalance coupled with mass spectrometer)
- TG-DSC-GC/MS (thermogravimetry, differential scanning calorimetry, gas chromatography / mass spectrometer)
Analytical techniques for coupling with thermal analyzers Coupling can be performed using various gas analysis methods:
- FT-IR spectroscopy
- Quadrupole mass spectrometry (QMS)
- ELIF spectroscopy (excimer laser-induced fragmentation fluorescence)
- Gas chromatography
The thermal analyzer can be coupled to the spectrometer/chromatograph in various ways:
- Heated transfer capillary (FTIR, GCMS, GC, MS)
- Sniffer coupling (GCMS, GC, MS)
- Optical in-situ observation (ELIF)
