Device for measurement of luminescence of a fluid sample
First Claim
1. Measurement device for effecting luminescence measurements of fluid samples, comprising:
- a sample plate including a plurality of sample vessels (20) having upper measurement openings (24) through which measurement light passes, said measurement openings having outer rim edges,a positioning device (14, 14'"'"') for positioning one of said sample vessels (20) in a measurement position,a transverse shield (42) including an inlet aperture (18) having an aperture opening (36), said transverse shield provided between said sample vessel (20) and a light detector (10),a light detector (10) for detecting the light passing through the aperture opening (36) of an inlet aperture (18) of said transverse shield (42),wherein when said transverse shield (42) is brought into engagement with the sample plate (16), it engages behind the outer rim edges of the measurement opening (24) of the sample vessel (20'"'"') found in the measurement position and separates it from the measurement openings (24) of the adjacent sample vessels (20).

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).
