A Horizon Instruments' Curie point pyrolysis unit was fitted to the head of a Hewlett Packard 6890 gas chromatograph with dual mass specific detection (MSD) (operated in scan mode over a range of 50-550 a.m.u.) and flame ionization detection (FID). A small amount of sample material was cold pressed onto a 610°C Curie point wire and flash pyrolyzed for 10 s. Products were directly transferred by a stream of helium onto a 60-m DB-5 capillary gas chromatography column and separated using the following temperature program: 50°C for 5 min ramped at 3°C/min to 350°C then held for 20 min. Resolved pyrolysis products were then split to the FID and MSD. Compound identification was confirmed by their mass spectra.
