Capillary holder used e.g. in micro-high performance HPLC has inlet and outlet waveguide parts fixed to a substrate

摘要

The inlet waveguide (16a) and the outlet waveguide (16b) are parts of a waveguide (16) that is fixed to a substrate (12) and interrupted in the region of the receiver by a notch (18) corresponding to the width and depth of the capillary to receive the capillary. Capillary holder (10) comprises a substrate (12) with a receiver for a capillary and an inlet waveguide for introducing light beams to the capillary and an outlet waveguide for receiving and further guiding of the light beams from the capillary to an evaluation unit. The inlet waveguide (16a) and the outlet waveguide (16b) are parts of a waveguide (16) that is fixed to a substrate (12) and interrupted in the region of the receiver by a notch (18) corresponding to the width and depth of the capillary to receive the capillary. An Independent claim is also included for a process for the production of a capillary holder.
