The vials used for the preparation of breath samples for automated solid-phase microextraction–gas chromatography–mass spectrometry analysis are crimped with septa. These septa often emit specific volatile organic compounds (VOCs) confounding the measurement results of breath samples.

Mar 31, 2022 · PTFE disk septa. A solid disk 0.010″ thick, our PTFE stands better than the most aggressive solvents. At least when it comes to chemical inertness. Most standard gauge metal HPLC needles can penetrate the thin membrane. Do not use PTFE septa with the following because you can’t release PTFE septa: 1. volatile solvents, 2. fast cycle periods,

Description. Chromatography septas can be pre-slit. A pre-slit septum is an ideal choice in applications requiring 20% or more of the sample injection each time from the vial so that suction is avoided. The slit allows ambient gas to equalize the gas in the vial so that a vacuum is not created in the vial from the tight seal around the needle.

make PTFE/silicone septa suitable for all types of chromatographic applications. A thin film of PTFE is laminated to the side of the septum that faces the sample to limit exposure of the elastomer to the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical.
