一般描述

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.
它是经典Thermogreen LB-1隔垫的改良版。

• 可以在较宽的入口温度范围内(100℃至350℃)保持极低流失
• 经过预处理，开封即用
• 易于进针，并具有较高的穿刺耐受次数(适用于自动进样)
• Supelco独有的橡胶材料配方

应用

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.

其他说明

对于之前采用 9mm 尺寸者,现在我们推荐 9.5mm( 3/8 英寸)的隔垫。
