Abstract
A method for making conduits includes inserting an inner tube into an outer tube and melting a portion of the inner tube to form a bond with the outer tube. The inner tube includes a polymeric material and the outer tube includes a material having a greater yield strength than the polymeric material. A conduit includes one or more inner tubes at least one of which is melt-bonded to one or more outer tubes. An analytical instrument includes a separation column, a solvent reservoir and pump, a sample injector, a detector to observe an eluent of the separation column, and tubing to transport fluid between components of the instrument.
