Sigma-Aldrich PRE-DRILLED THERMOGREEN LB-2 11MM PK25

Sigma Aldrich 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.[1] 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.[2], Use pre-drilled septa for SPME applications to reduce septum coring., 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.[3], Thermo-resistant septa is used in GC instrument to avoid carrier gas leaks, extraneous peaks and phthalate contamination.[4], t hermo-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], Legal Information, Thermogreen is a registered trademark of Merck KGaA, Darmstadt, Germany - SIALGSK (Additional S&H or Hazmat Fees May Apply)
