설명

일반 설명

An improved version over the original Thermogreen LB-1 septa.

• 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

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.

애플리케이션

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 instrument 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.
