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.
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

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.

One of the responses that honey bee workers can make in the event of queen loss is to develop into false queens. False queens are workers that exhibit both behavioural and physiological traits similar to those of a true queen.
