General description
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 introducing 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.
These low cost gray silicone rubber septa are designed for routine, isothermal use. For use with 50 °C to 200 °C inlet temperature.
Application
GR-2 septa were soaked in either a control or Pieris mixture for an hour proceeded by bioassays with synthetic scent compounds.
