General description

For use with 50 °C to 300 °C inlet temperatures.

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.

Application

Thermogreen^® LB-2 Septa is suitable for the following applications:
• To minimize extraction onto or loss of analytes off the solid phase microextraction (SPME) fiber from the vial during analysis by GC-MS.
• Thermo-resistant septa is used in GC instruments to avoid carrier gas leaks, extraneous peaks and phthalate contamination.
• Thermo-resistant septa along with thick needle protector is used in GC instruments to avoid damage irreversibly caused by microsyringe.
• It is also used in the influent sampling ports in gas chromatographs.
