ABSTRACT:
End caps that are press fitted to the ends of an analytical column tube and to a precolumn tube are abutted to form a fluid flow path. The end caps include projections around the fluid flow path to form a void between the opposing faces of the end caps. A gasket seal is retained within the void to provide a seal for confining pressurized fluid to the flow path. The analytical column extends into a stepped bore in a holder body. A wider diameter portion of the stepped bore receives the analytical column end cap and provides a stop for supporting the compressive load required to maintain the seal.
