Thermo Fisher, 290GA082, 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 a single-column split/splitless GC inlet while reducing activity at the injection-port interface. This configuration is a gold-plated base seal machined from high-grade stainless steel with a 0.8 mm internal diameter. The package contains two seals, making it suitable for small maintenance inventories or a limited number of inlet replacements. A precision-machined sealing surface supports reproducible inlet assembly, and the chemically inert coating limits unwanted interactions with active compounds such as pesticides, polychlorinated biphenyls and phenols. The base seal is compatible with appropriate Thermo Scientific TRACE 1300 Series GC injection ports and Agilent 5890, 6890 and 7890 split/splitless GC inlet systems. It is intended for single-column installations rather than dual-column hardware. This part replaces a GC inlet base seal and is not a septum, liner or column ferrule. The 2-pack quantity is the principal difference from the larger package of the otherwise comparable gold-plated 0.8 mm single-column seal.
