The injection port,oven,and detector of the GC unit were operated at 200°C. The retention time for m-CB was 3.83 min. The area of the peaks in the chromatograms was determined by an HP3396A integrator (Hewlett-Packard,Paramus,NJ) to which the GC unit was connected. The GC calibration was repeated on a weekly basis.

GC Injector Septa-HRGC

The septum is used to seal the injection port and it is an interface for injecting the sample. The septa are made of polydimethylsiloxane-a similar polymer is used for stationary phases. When heated,such siloxane polymers will form degradation products that will show up in the GC analysis.
