Patent ES-2219962-T3 (ES)
Inventor: QUAPIL GERALD DR
IPC: G01N21/55

Granted: 2004-12-01
Abstract: Boundary surface (7) is formed by the upper surface of the cuvette (2) base. The cuvette has the form of a solid body, with the base accepting the assay medium. Transmitted light rays (3) are coupled in through a side wall (6) of the base, such that they reach the boundary surface (7) at the angle of total internal reflection. Preferred features: The base includes two plane opposite walls at an angle less than 90 degrees to the boundary surface. Light enters one, and after total internal reflection at the base surface, leaves by the other. The sidewalls are symmetrical about the plane of symmetry of the cuvette. The cuvette is essentially hollow cylindrical, the plane sidewalls forming angles in the cylindrical base. Open at the top, the cuvette has an upper panel forming a top section, which is inserted in a holder. The panel is rectangular, the holder fastening to the longer sides. A side edge of the panel is marked to indicate the cuvette contents. The cuvette is one-piece; a plastic injection molding. The transmitted rays (3) outside of the cuvette, run parallel to the boundary surface of the cuvette. The fluorescence rays (9) are coupled out through the underside of the cuvette base, and are led to the receiver (10). The transmitter (4) is arranged facing a sidewall (6) of the cuvette base. The transmitted rays, after leaving the cuvette (2) are led onto an optical sink (8). Mirrors with polarization filters can be arranged to send the rays repeatedly through the apparatus. The apparatus includes many cuvettes in the light paths from individual transmitters. Fluorescence rays from the individual cuvettes, are registered by a common receiver (10). Transmitters are activated individually and sequentially. The cuvette arrangement is linear. The cuvettes are alternatively arranged around a polygonal mirror taking fluorescence light to the receiver.
