Septum is a very important component of syringe injection system. They are usually fabricated from elastomeric, self-sealing materials such as silicone rubber, neoprene or fluoroelastomers. It is suitable to conveniently introduce the sample without causing the system to leak. Improper septa decomposes under the high-temperature conditions of capillary inlets causing baseline disruption and ghost peaks in a chromatogram. Use pre-drilled septa for SPME applications to reduce septum coring.
