Thermo Fisher, 290GA081, GC Injection Port Base Seals for Thermo Scientific™ and Agilent Instruments

GC Injection Port Base Seals for Thermo Scientific™ and Agilent Instruments is designed for sealing split/splitless gas chromatography inlet assemblies used with a single installed column. This version is a gold-plated inlet base seal precision-machined from high-grade stainless steel, with a 0.8 mm internal bore. The pack contains 10 individual seals. Its inert gold-coated surface reduces analyte interaction in the inlet and is particularly relevant to measurements of active compounds such as pesticides, polychlorinated biphenyls, and phenols. The seal helps establish a reproducible mechanical interface at the inlet base while minimizing undesirable activity that could affect chromatographic response. It is intended for compatible Thermo Scientific TRACE 1300 Series GC systems and Agilent 5890, 6890, and 7890 split/splitless injection ports. The design is for a single-column installation, not the larger-bore dual-column version. The 10-pack format suits laboratories replacing inlet seals during routine preventive maintenance or when troubleshooting leakage and inlet activity. Correct component geometry and inlet compatibility are important because a base seal is not interchangeable with a septum or a capillary ferrule.
