General description
- Extremely low bleed over a wide range of inlet temperatures (100 °C to 350 °C)
- Already conditioned, ready to use
- Easier needle penetration and high puncture tolerance (ideal for autosamplers)
- Rubber formulation exclusive to Supelco
Application
- To minimize extraction onto or loss of analytes off the Solid phase microextraction (SPME) fiber from the vial during analysis by GC-MS.[3]
- Thermo-resistant septa is used in GC instrument to avoid carrier gas leaks, extraneous peaks and phthalate contamination.[4]
- Thermo-resistant septa along with thick needle protector is used in GC instruments to avoid damage irreversibly caused by microsyringe.[5]
- It is also used in the influent sampling ports in gas chromatographs.[6]
