Abstract
A capillary column includes a fused silica tubing, a polyimide coating over the fusing silica tubing, and a first plurality of integrated ferrules positioned along at least a first portion of the fused silica tubing and spaced apart from one another by a first fixed interval. Each of the first plurality of integrated ferrules includes a first deformable surface and a second deformable surface. The first plurality of integrated ferrules are secured to the column through deformation of the first deformable surface and the second deformable surface is configured to form a seal with a junction when secured with a nut.
