Abstract:
The circuit comprises an inlet (3) for the injection of a sample of material to be analyzed into the circuit, cuvettes (6, 7, 9, 11, 12) filled with fluid compositions intervening in the analysis of the sample and a network of ducts (4, 6', 8, 13, 14) for the flow of the fluids present in the circuit. The inlet (3), the cuvettes (6, 7, 9, 11, 12) and the ducts (4, 6', 8, 13, 14) each comprise a wall element that is deformable between a first position where it allows the presence of a fluid under its surface and a second position where it is applied against a nondeformable surface placed opposite it, after expulsion of the fluid contained between said surfaces.
Abstract:
An optical waveguide component (42), with a pigtail (40) attached thereto, is disclosed in which a portion of a surface (46) of the component is bevelled and a portion of the endface (44) of the pigtail is bevelled. The bevelled portion of the pigtail endface is oriented to be substantially parallel to the bevelled portion of the component surface or is oriented to be open with respect to the component surface. The pigtail endface can be continuously bevelled to form a substantially conical shape on the pigtail endface, wherein the substantially conical shape is offset from the optical axis of the pigtail. Adhesive or gel (43) is used to attach pigtail (40) to component (42).
