Abstract
The invention relates to tubing assemblies and methods for forming a fluidic connection to make the same. The assemblies include an outer tube having disposed therein a first inner tube affixed to the outer tube, a second inner tube and a support tube disposed in the second inner tube. The second inner tube is abutted against the first inner tube. A radial crimp is made in the outer tube over the second inner tube a distance x from where the tubes abut; the distance x being such that the end of the second inner tube seals against the end of the first inner tube. Various embodiments provide assemblies suitable for use with high fluidic pressure (e.g., greater than an about 70 MPa, approximately about 10,000 psi) and formation of chromatographic column assemblies comprising a capillary tube predisposed within the first or second inner tube prior to formation of the seal.
