General description

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°C至350°C）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

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 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.

Other Notes

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。

The sonochemical degradation of aqueous solutions containing low concentrations of six phthalate esters at an ultrasonic frequency of 80 kHz has been investigated. Ultrasonic treatment was found capable of removing the four higher molecular mass phthalates (di-n-butyl phthalate, butylbenzyl phthalate
