NANO-FLOW LIQUID CHROMATOGRAPHIC APPARATUS HAVING ROBUST CAPILLARY TUBING

摘要

A chemical processing apparatus includes a separation column, a pump unit configured to support nano-flow processing, at least one fluid transport tube for transporting the fluid between the pump unit and the separation column, and a connector disposed adjacent to an inlet or outlet end of the at least one transport tube. The fluid transport tube and/or the separation column includes an outer tube of a metallic material, a fused-silica capillary disposed in the outer tube, and an intermediate tube including a polymeric material disposed between and bonded to both the outer tube and the capillary.
