Column Connectors

Column connectors are useful for attaching a guard column/retention gap to an analytical column, or for repairing a broken column. Modern connectors are precisely designed to provide highly reproducible taper angles, ensuring an excellent seal. Column connectors are typically treated to provide a robust and inert flow path. Column connectors are available in a variety of design shapes and fabrications for compatibility with a wide range of GC systems and applications.
