Abstract
A fitting assembly (100) is provided. The fitting assembly (100) comprises a holder (102) that holds one or more fluidic seal assemblies. The fluidic seal assembly comprises a fitting (104), a ferrule (110) and a tube (112), such as a chromatography column, and optionally comprises a protrusion (118) and a compliant seal material (120). Fluidic connections for a gas chromatography instrument are also provided.
Claims18
A fitting assembly comprising:
- one or more fluidic seal assemblies, wherein each fluidic seal assembly comprises:
- a fitting comprising an inside fitting wall that defines a fitting bore,
- a ferrule comprising an inside ferrule wall that defines a ferrule bore, and the ferrule is disposed in the fitting bore;
- a tube comprising first and second tube ends, and one of the tube ends is disposed in the ferrule bore;
- wherein the ferrule is in compressive contact between the inside fitting wall and the tube so as to form a seal;
- a holder comprising a cavity wall defining a cavity where the tube passes through the cavity;
- wherein each of the fluidic seal assemblies is held by the holder, and
- the fitting comprises first and second fitting ends and an outside fitting wall between the first and second fitting ends;
- the fitting further comprises a protrusion at the first fitting end, and the protrusion defines a protrusion flow path, and each of the fluidic seal assemblies further comprises a compliant seal material around the protrusion.

A chromatography column assembly comprising:
- a chromatography column having first and second column ends;
- and
- one or more fluidic seal assemblies, wherein each comprises:
- a fitting comprising an inside fitting wall that defines a fitting bore,
- a ferrule comprising an inside ferrule wall that defines a ferrule bore, and
- the ferrule is disposed in the fitting bore;
- wherein one of the column ends is disposed in the ferrule bore, and the ferrule is in compressive contact between the inside fitting wall and the column so as to form a seal;
- a holder comprising a cavity wall defining a cavity where the chromatography column passes through the cavity;
- wherein each of the fluidic seal assemblies is held by the holder, and
- the fitting comprises first and second fitting ends and an outside fitting wall between the first and second fitting ends;
- the fitting further comprises a protrusion at the first fitting end, and the protrusion defines a protrusion flow path, and each of the fluidic seal assemblies further comprises a compliant seal material around the protrusion.
