Description

General description

Use pre-drilled septa for SPME applications to reduce septum coring.

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.

GC Injection Port Issues: Two Case Studies (Peak Tailing and Low Response)

Introduction For the vast majority of uses, samples pass through an injection port at the start of the gas chromatography (GC) process. Therefore, it is very important to ensure that the proper injec...

GC Septa Use and Maintenance Tips

A GC septum is located at the top of the injection port and serves two functions: 1) providing a leak-free seal to maintain carrier gas pressure inside the system 2) handling repeated puncturing by a...
