Injector septa used in Gas Chromatography provide a critical role in maintaining system isolation but allow the sample to be introduced onto the column in a Quantitative manner.
Since the injector septa provide the seal between the inner workings of the injector and the laboratory environment, it must have several desirable characteristics.
