GC injection port split septum

Offer a wide range of gas chromatography (GC) injection port septums, O-rings and injection port gaskets. They work together to ensure that the sample fully volatilizes and introduces the analyte into the chromatographic column.

The NWSPEC gas chromatography septum separates the sample flow path from the metal walls of the injection module. Various gas chromatography injection port septum geometries and packaging materials meet the different sample volatilization requirements. Choosing the appropriate injection port septum is crucial for ensuring that all target analytes are rapidly vaporized and transferred to the analytical column without adverse interactions or degradation, thereby avoiding injection port discrimination. NWSPEC provides multiple gas chromatography injection port septums for each NWSPEC injection port configuration: S/SL, MMI, PTV, and HS, etc.

The O-ring of the Agilent injection port liner serves as the foundation for creating an appropriate seal between the liner exposed to the injection port weld and the pivot-type cap. These sealing components are designed to separate the carrier gas and the split gas flow from other instrument flow paths. Agilent's unique plasma coating process helps form a barrier, thereby better protecting the base elastic material and preventing any adhesion between the injection port weld and the liner.

The NWSPEC split plate with unique ultra-high inert deactivation technology can provide a leak-free connection at the bottom of the inlet. This further prevents the loss of active analytes during the vaporization process due to adsorption or decomposition. The soft gold-plated outer layer ensures proper mechanical sealing without damaging the inlet hardware or adjacent inlet liners.
