GC Injector Septa-HRGC

GC Septa 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.
