13 14 Pyrolysis-gas chromatography (Py-GC) has become well established as a simple, quick and reliable 15 analytical technique for a range of applications including the analysis of polymeric materials. Recent 16 developments in Py-GC technology and instrumentation include laser pyrolysis and non-discriminating 17 pyrolysis. Progress has also been made in the detection of low level polymer additives with the use of 18 novel Py-GC devices. Furthermore, it has been predicted that future advances in separation technology 19 such as the use of comprehensive two-dimensional gas chromatography will further enhance the 20 analytical scope of Py-GC. 21 22
