General description

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.

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
