Pyrolysis-Gas Chromatography-FT-IR

Whilst pyrolysis-gas chromatography (Py-GC) is a very important analytical tool for the elucidation of polymer structure, the technique becomes even more useful when it is coupled with complementary techniques such as infrared (IR) spectroscopy and more recently mass spectroscopy (MS) (see Chapter 3). These techniques, particularly MS can be used to provide unequivocal identification of volatile pyrolysis products produced on pyrolysis or of individual pyrolysis products separated by GC. 

This technique has many applications in qualitative and quantitive thermal analysis degradation studies and polymer microstructure studies [1-3]. 

The possibilities for polymer characterisation using a dispersive spectrometer have recently been developed [4], The technique is similar to the thermal volatilisation
