Abstract: A measuring system and method are provided for performing luminometric series analyses on reaction components to be investigated and the liquid samples containing the magnetizable carrier particles binding said components. Sample chambers receive the liquid samples. These sample chambers are transported to a measuring station on a conveyor. Permanent magnets act on the sample chambers with magnetic fields during transport. A separating station is also provided, which is preferably equipped with a suction and rinsing device to remove the surplus reaction components separated from the carrier particles that accumulate on wall areas of the sample chambers under the influence of the magnetic fields.

Abstract: The invention concerns a measuring device for carrying out of luminescence measurements of fluid samples, with a light detector (10) which detects the light entering an aperture opening (36) of a inlet aperture (18) and a positioning device for positioning one of a multiplicity of sample vessels (20) arranged on a micro-test plate (16 with respect to the aperture opening (36). In order to prevent the spill-over of light between the individual sample vessels (20), a transverse shield (42) is provided capable of being brought into engagement with the sample plate, which in the engagement position separates the measurement opening (24) of the sample vessel (20') found in the measurement position from the measurement openings of the adjacent sample vessels (20).
