ALL GC Models. 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. Such peaks are called “ghost peaks”.
