Evolved Gas Analysis (EGA)

Evolved Gas Analysis (EGA) is a technique for structural analysis of gasses and vapors evolved when a sample is subjecte d to controlled heating. EGA instrumentation employs on-line coupling with FTIR, MS, GC-MS and TGA or DSC systems enabling simultaneous compositional, mass balance and calorimetric analysis. This technique finds use in analysis of a large variety of materials. The vast laboratory network of Infinita Lab, USA, offers this test to clients in the USA and across the world.... Read More

    Evolved Gas Analysis (EGA)

    Evolved Gas Analysis (EGA) is an analysis technique that determines the nature and amount of volatile product or products evolved from a sample subjected to a controlled temperature program. Vapors released from the sample due to processes such as evaporation, decomposition o r outgassing of inclusions during thermal treatment are immediately transferred through an interface, to the evolved gas analysis (EGA) system. The EGA system can utilize a variety of  instrumentation such as Fourier Transform Infrared spectroscopy (FTIR), Mass Spectrometry (MS) or combination of MS with gas chromatography (GC-MS). Simultaneous thermal analysis using techniques such as  TGA (thermogravimetry) or DSC (differential scanning calorimetry), can also be done, coupled with a fast Quadrupole Mass Spectrometer (QMS). This enables identification of the evolved gas components and real time correlation with the other thermal analysis parameters. In case directly coupled EGA systems are not available, then, the evolved gasses can suitably be captured, for example, in an adsorbent followed by thermal desorption for off-line analysis.

    EGA is widely used for polymer/plastics samples that contain a variety of additives, such as flame retardants, fillers, plasticizers, coloring matters, and antioxidants. The EGA technique has also been applied to other materials including chemical, pharmaceuticals, biomass, and various organic and inorganic compounds.
