    摘要: Described is a chromatography column assembly that includes a permanently deformable outer tube, an intermediate tube, an inner tube and a sorbent bed disposed within the inner tube. The sorbent bed may be in the form of packed chromatographic particles or a porous monolithic structure. A radial seal is provided by one or more uniform radial crimps at longitudinal locations on the assembly. The uniform radial crimp compresses the outer tube and underlying intermediate tube onto the inner tube to achieve a high pressure liquid tight seal between the three tubes. The length and depth of each crimp is accurately formed to accommodate the requirements of the particular application. Leakage along the tubing assembly is prevented and void volume is reduced or eliminated. No external ferrule or ferrule swaging mechanism is needed; therefore the chromatography column assembly is easily adapted for use in various chromatographic column configurations.

    摘要: Described is a chromatography a chromatography apparatus that includes a microfluidic substrate, a coupler and a sealing fitting. The microfluidic substrate can include one or more chromatography columns, such as analytical columns or trap columns, and an inlet in communication with the one or more chromatography columns. The coupler is diffusion bonded to the surface of the microfluidic substrate so that an opening in the coupler is aligned to the inlet in the microfluidic substrate. The sealing fitting includes a heat-resistant sealant disposed in the opening of the coupler and in contact with the surface of the substrate. The coupler and sealing fitting enable a compact fluid-tight connection to the inlet of the microfluidic substrate that exhibits high tensile and torsional strength, and does not require the use of adhesives.

    摘要: Described is a tubing assembly which includes a permanently deformable outer tube, an intermediate tube and an inner tube. A radial seal is provided by a uniform radial crimp having a non-zero longitudinal length at a longitudinal location on the tubing assembly. In some embodiments one or both ends of the assembly have a uniform radial crimp and are polished so that the ends of two or more of the tubes are substantially flush with each other to thereby block the passage of fluids between the ends of the tubes. In other embodiments the uniform radial crimps are at other longitudinal locations where a high pressure seal is desired. The longitudinal length and the depth of each uniform radial crimp can be formed to accommodate the requirements of a particular application so that leakage along the tubing assembly is prevented and void volume is reduced or eliminated.

    摘要: Described is a reusable fitting for attaching a conduit to a port. The fitting includes a housing, a spring, a retainer and a cap. The retainer is capable of locking and unlocking a conduit in the fitting. The fitting provides a high pressure fluid-tight seal and a substantially zero void volume at the junction of two fluidic conduits. The fitting is removable, reusable and replaceable, and allows a user to make and remake connections of a capillary to a fluidic port without permanently binding a ferrule to a specific capillary and thus to a specific port. The fitting can be replaced if part or all of the fitting is damaged during use.
