Descrizione generale
PTFE-faced septa are designed for applications where greater inertness is required. The off-white silicone rubber body (123 mil thick) provides plenty of support for the yellow PTFE face (2 mil thick). After the PTFE is ruptured during injection, some bleeding may occur. Because this bleed increases as more of the rubber is exposed, we recommend using a needle guide to reduce the size of the punctured area. For use with 200 °C to 300 °C inlet temperatures.
PTFE-faced septa are suitable to overcome the degradation due to prolonged high temperatures which occurs in silicone rubber septa. The degradation results in baseline drift and additional peaks. It is generally fixed with the PTFE faced towards the column packing.[1]
Applicazioni
Glass vials equipped with stir bars may be sealed with PTFE faced silicone septa, for solvent drop microextraction analysis of water samples.[2]
