Recent Applications of Evolved Gas Analysis by Infrared Spectroscopy (IR-EGA)

A correct interpretation for the mechanism of a thermally induced reaction, involving the formation of gaseous species, is strongly dependent on the characterization of the evolved products.The analytical applications of evolved gas analysis (EGA) performed by infrared spectroscopy (IR-EGA) for the period 2010-2012 are reviewed in this article. When the nature of volatile products released by a substance subjected to a controlled temperature program were determined on-line, the results proved a supposed reaction, under either isothermal or heating conditions.
