Conclusions

Despite the early stigma of unreliable and dirty analysis, PGC survived because of the dedication of a small handful of workers who were convinced that most practitioners were to blame for their failures rather than the tool they purported to use.

The method has re-emerged as an active member of the analytical chemist's armoury. This is handsomely substantiated by each successive issue of the Journal of Analytical and Applied Pyrolysis.

Material gain has resulted from the adoption of hyphenated instrumentation (e.g. coupling with high speed quadrupole mass spectrometry or Fourier transform infrared spectrophotometry) and has most certainly elevated the status of the technique.
