Abstract:
1. A method of bonding a first fluid conduit to one or more other fluid conduits comprising: positioning a first fluid chromatography conduit portion substantially in contact with at least one other fluid chromatography conduit portion to form a substantially direct interface between the first fluid chromatography conduit portion and the at least one other fluid chromatography conduit portion; heating a bond region at a surface of each of the first fluid chromatography conduit portion and the at least one other fluid chromatography conduit portion; externally applying a solid thermoplastic polymer to the bond region; liquefying the solid thermoplastic polymer, wherein each of the first and at least one other fluid chromatography conduit portions is heated to a temperature at which the solid thermoplastic polymer liquefies, without melting the conduit portions; maintaining the first and at least one other chromatography conduit portions at the temperature for a predetermined amount of time to achieve liquefying of the thermoplastic polymer and bonding of the thermoplastic polymer to the first and at least one other chromatography conduit portions; and cooling the liquefied thermoplastic polymer to form a substantially fluid tight bond at the bond region between the first fluid chromatography conduit portion and the at least one other fluid chromatography conduit portion, wherein the cooled thermoplastic polymer surrounds the interface.
