Abstract:
1. An analytical instrument fitting assembly for coupling first and second analytical fluid conduits, the fitting assembly comprising: (a) a first fitting defining a central passage adapted to receive a first fluid conduit defining an internal diameter of no greater than 0.040 inch; (b) a second fitting defining a central passage extending between first and second ends and is in fluid communication with the first fitting; (c) a coupler releasably connecting the first and second fittings by application of a coupling force to the coupler, wherein the coupling force is substantially within a range of 0.1-5.0 inch-pounds; (d) a separation device disposed within the central passages of the first and second fittings to selectively separate liquids passing therethrough; (e) a retractable end fitting at least partially disposed within the second end of the second fitting, the retractable end fitting having: (f) a restraint slidingly engaging at least one of the second fitting and the housing to prevent rotation of the housing relative to the second fitting, wherein movement of the housing relative to the second fitting is limited to a longitudinal direction.
