Emission gas analysis
The emission gas analysis or emission gas thermal analysis ( evolved gas analysis , EGA ) is a method of thermal analysis in which a sample undergoes a change in temperature and gases released are analyzed. If the amount of gaseous release only recorded to analyze qualitatively without this, one speaks of an emission gas detection (engl. Evolved gas detection , EGD ).
The EGA is suitable for measuring combustion processes , decomposition reactions or degassing processes .
FTIR spectrometers , gas chromatographs or mass spectrometers are mainly used to analyze the emitted gases . Combinations of the analysis devices make it possible to eliminate the disadvantages of individual methods.
The emission gas analysis is usually combined with other thermal analysis methods.
