Definitions

  • the present invention is concerned with an analyzer for the measurement of the properties of reaction mixtures contained in the cuvettes in a set of cuvettes simultaneously out of several cuvettes by means of one or several sources of radiation placed above or underneath the cuvettes and by means of a detector receiving radiation and placed underneath or above each cuvette, the beam of measurement passing substantially in the direc tion of the vertical axis of the cuvette and the set of cuvettes being fitted to the apparatus detachably between the source or sources of radiation and the detectors, either above the source, or sources of radiation or above the detectors.
  • the objective of the invention is to provid a compact and simple construction of an analyzer.
  • the analyzer in accordance with the invention is characterized in that either the detectors or the source or sources of radiation, respectively, can be fitted detachably or pivotably to the position of measurement above the set of cuvettes.
  • FIG 2 shows one cuvette and the source of radiation and the detector placed underneath and above the cuvette, respectively.
  • the analyzer comprises a base 1, a frame 2, and a measurement head 8 permanently fixed to the frame, the said measurement head being provided with several optical fibres 9 functioning as sources of radiation.
  • the detector matrix 3 is by means of the cable 4 connected to the apparatus. When the apparatus is not in use, the detector matrix 3 is fitted into a recess 18 in the frame placed at the side of the measurement head. The measurement takes place so that the cuvette set 7 is placed onto the measurement head 8 and that the detector matrix 3 is thereupon shifted onto the cuvette set.
  • the cuvette-set matrix may also be measured in an analyzer embodiment in which the detector matrix is stationary or in which some component of the detector matrix moves in the measurement head.
  • the cuvette-set matrix can be placed onto the detector matrix, and the measurement-beam matrix is shifted or pivoted onto the cuvette-set matrix, in which measurement-beam matrix there is a source of measurement signal of its own for each cuvette.
  • the said shiftings and any other manipulations can also be performed automatically in the way most appropriate in each particular case.
  • the measurement radiation may also be produced by means of some appropriate wide source of radiation so that one or, at the maximum, few sources of radiation are required.
